I remixed another person's design of a Catan piece holder.  The newer game pieces seem to be a little large and will not fit the provided holes (settlements) so I imported and converted the STL in Fusion 360 and increased the hole size for the settlements (it's up on Thingiverse).

Another user asked for a cover/lid so I designed one that fits over the piece holder and keeps the pieces secure inside.  I haven't posted it yet because I need to do a tiny tweak so the lid is easier to remove and doesn't require any post-print trimming/sanding (at least with an extruder print).

Here's the piece holder:

I have a 3D printer and a 3D pen that my grandkids gave me that I have no idea what to do this, so I'm going to get a kick out of these replies.

My kickstarter printer (https://jgmaker3dofficial.com/produc​ts​/artist-d ) is giving me some teething issues. I'm having trouble getting e-steps right. Well, I have them calculated but the printer is way over extruding. I have the flow rate down to like 75%. It's almost like I have the wrong size nozzle in it. Hopefully I'll be able to figure it out because the printer is actually nice and the future for it looks promising.

I wish I had a resin printer. I finally dialed in the perfect PETG settings on my Ender, and I'm ready to move up.

What is the brand and model?

YouTube up tips and tricks for your printer but most importantly, look up the best filament to use for your printer model and how to level the bed (if it doesn't have auto-leveling).

Get a copy of Cura (free) - it's a "slicer" which is basically a print preview for 3D printing.  You only need to start with a handful of the hundreds of settings available (you can select those you want to be available all the time).

Print out "3DBenchy" or the "test dog" and this will reveal immediate issues that can be easily looked up/googled (i.e., "3D Benchy melted on top...what's wrong?").

Go to Thingiverse and get a printer test and print it for more detailed tweaking of your printer settings.  I like the following:

That is nice.  Maybe you have a filament it doesn't like?  I know I used to get *under* extrusion on that Amazon Basics PLA crap unless you put the temp at like 215 or better.  And that setting would over-extrude Hatchbox for sure.

If it was a 10% swing in either direction I wouldn't be as concerned and would associate it with crappy filament given with the printer. I have some of my general economy brand on order (Tecbears). On my other printer I have it dialed in really well so it has a bit of a "known quantity to it". I'm more concerned that there is something silly going on with the extruders, slipping, missed steps, or other some such nonsense.

We've been using these lately and they work really well: https://www.amazon.com/Creality​-Photoc​uring-Filtering-Off-line-Printing/dp/B​082XDH8NB

Small build volume of course, but good detail and they Just Work, as opposed to the $5k resin printer I bought 5 years ago.

Do keep in mind resin is a lot nastier to deal with than filament- good ventilation and a place that will handle spills and cleanup are essential

I have the wierdest problem with mine right now.

I have a Printerbot Simple Metal that I have upgraded with heated bed , E3D hot end and a Nozzle X nozzle.

Works great, every kind of filament I have sticks great on just blue painters tape - except one.

A roll of purple  PLA I bought from the supplier I usually get filament from.  I have other colors of the same type, no problem.  Just can't get this purple to stick worth a damn.

I'm genuinely curious, besides making figurines, artwork, knick-knacks or models, what kinds of things are people making with 3D printers at home? Do you make practical things instead of buying them at a store? As cool as the printers are, I can't think of a reason why a typical person would need one at home.

I've made pieces and parts for my 3d printer. I've also made enhancements for my reloading press, plus a bunch of miniatures, figurines and busts. I'm going to print some frames for firearms once I upgrade to be able to print with glass reinforced nylon.

Hardly a week goes by where I haven't needed it.  And I've never made a figurine in four years.

This weekend it was an assembly jig to rebuild a battery pack for a drill, and a mold for silicone to encase a piece of electronics that will be outside.

Generally, I use it to support other hobbies and fix things in the home.

Useful little buggers.

Bear in mind that my ADD-addled brain loves to make grand plans that I never carry out but still hang onto for decades, so I'll most likely never getting around to fulfilling this dream I've had since about 1980, but ...

A lot of people print replacement parts for little pieces that break on something you don't want to have to buy a whole new unit for but would be perfectly usable but for that one broken piece.

Clips, nozzles, brackets, bezels, thumb wheels, replacement planetary gears, replacement bushings, fan blades... Just to name a few things you could practically use this for...

Then there's the assistance for other DIY projects... example if you like making things out of say PVC but need a specific angled coupler that you can't pick up at the hardware store, you could one out, or lets say you need to join two different types of pipes one PVC and one metal conduit, and they have different exterior diameters, print out a coupler for that too...

You are only limited by your imagination and the print bed size...

Did you check that you have the right filament diameter in the slicer, and that you don't have the microstepping set wrong in the firmware or on the board?

There are SO many settings to chase, it's easy to miss one.

My favorite thing I did with my 3D printer after designing and building it was when I broke the kitchen faucet at 9PM in the middle of doing dishes on a weeknight.

There was a broken little plastic clip that connected the lever to the cartridge. I was wandering around the house trying to figure out what to do when I realized that I had a way to fix it. A half hour with calipers and Solidworks, and the part took 10 minutes to print. Second prototype was perfect, and is still making that faucet work as far as I know.

I've got tons of shelves around the house held up with 3D printed brackets. Need a custom coat hook? BAM! Need another one? POW!

Do you make practical things instead of buying them at a store? As cool as the printers are, I can't think of a reason why a typical person would need one at home.


Here are a *few* of the practical, around the house, things I've done:

https://www.thingiverse.com/thing:154​8​854 (Spray can hold - have a ton of these in garage)
https://www.thingiverse.com/thing:281​4​968
https://www.thingiverse.com/thing:330​1​51
https://www.thingiverse.com/thing:204​7​093 (I use the hell out of this)
https://www.thingiverse.com/thing:305​9​460 (very handy for Handpresso outdoor/portable espresso maker)
https://www.thingiverse.com/thing:282​3​143 (wife loves this because the Renegade console doesn't come with one)

Again, that's just a few.  I've done wall panels, cord organizers, parts for cars (push pins, panels, s-hooks, clips), echo-dot wall holders, HTC Vive accessories, trout lure dividers for Altoid tins (*really* handy), nozzles for cake icing bags, connectors for air hoses, a farking yard drain (connected to 1.5 pvc)....  I've been using a 3D printed no-touch door opener since the beginning of the pandemic.  I've only just stopped using the 3D printed N95 mask I zapped out during the mask shortage (seal tore).

Thingiverse's search is a little wonky today but there are just tons of things for every day use that you will probably find handy or useful.

And there are tons more things that are neat and fun that aren't figurines.  A few months ago, I needed an adjustable stand for my son's science project - it needed to hold a hall effect probe in a fixed spot.  I have a button box for an X52 joystick/throttle that adds a load more usable buttons (needs HID recognized Ardunio), I built the "halloween eyes" (google it) project which required 3D printed parts.

Sorry for the long message but it's really cool/fun/educational/etc.  I highly recommend.

That's weird.  I wonder what the purpose pigment does to it.  I don't know off the top of my head (anything I said would be a guess).

I have BuildTak on some 1-2mm fiberglass which is clipped to my heated plate.  The only time I have adhesion problems is when I don't have a good level.  But I haven't tried a wide variety of colors and brands - I'm going to get a roll of Overture soon and see how that works.

I keep on thinking I should get a 3D printer, and then I can't think of a single thing I would actually use it for.

The only thing I can think of would be making parts for costuming and cosplay, and I don't really do that except at halloween.

All sorts of things, and it's still in the hobbyist phase where designing and printing something is fun in itself. Two days ago I couldn't find the cleaning disc for my Tassimo coffee maker so I thought of printing one, then wondered if the plastic would cope with hot steam pumped through it. Ended up buying one on Amazon for £2.50.

So that's my cool story about how I almost thought of printing something but bought it instead.

Ya. I double checked that because I've made that mistake too! It's really driving me insane because this printer is a ton higher component quality than my Ender 3 Pro was. However, I'm still astonished at the quality of print I was able to get off the Ender 3 without doing anything other than leveling the bed.

I've found these cheaper printers to be extremely reliant on the OSS community. A lot of their default setting aren't tweaked from the defaults in Marlin. I guess it's part of the fun for me, figuring out how to make it better. However, there are times that I just want things to "work as advertised".

That part is even more fun for me than actually making things.

But yeah. When something breaks I just want it fixed, not to fiool around with a printer that won't print right.

Yeah, printers are fun, but they are still very much a "hobby" device, not a consumer product. When  you buy a toaster you expect it to work. With 3D printers you will have prints fail, for all sorts of reasons. And you have a hundred settings to play around with.

I'd gone ages without printing anything, the printer was packed away, and when I recently got it out it would not print. The feed motor kept on jamming, making a juddering noise. Tried everything. Then I changed the filament for a new vacuum sealed pack and it worked perfectly. Turns out filament goes bad. Who knew?

I just got an Ender 3 (won it in an internet raffle). I'm just starting to get it put together and thankful for all the internet how-to videos because the Engrish assembly instructions are a bit lacking.

Anybody have advice on little (or big) things they wish they had known when they were getting started?

With respect to the Ender 3 and YouTube searching, you're going to run into the huge breasted Chinese girl (Naomi Wu).  While she is fun to look at, there are better tutorials/info.

I wish I could remember the link but I put mine together based on a build video rather than any instructions that come with it.  The most important step is to grab the top, with it sitting on a very flat surface and with the base screws just barely tightened, and shake it until it is level then snug the screws down.

Also, be sure to bed level on a heated bed.  I don't know about the newer Ender 3 printers but mine (along with lots of people with my printer) has a warped bed that straightens out, for the most part, when heated.  This may be the norm now, I don't know, but it's better to do that when heated.

Here are some of the accessories for my Ender 3 that I printed immediately and use constantly:

I'd gone ages without printing anything, the printer was packed away, and when I recently got it out it would not print. The feed motor kept on jamming, making a juddering noise. Tried everything. Then I changed the filament for a new vacuum sealed pack and it worked perfectly. Turns out filament goes bad. Who knew?


PLA - it goes brittle as hell.  If I have an old, almost used, roll and I let it sit on the printer for a week, the filament will snap (sometimes).

Print this:

And use this in it:

Blue Silica Gel (Indicating)


Put that in the center of a partially used or open filament roll and toss everything into a zip-loc or vacuum bag.  It should "revitalize" old PLA as well.

I have a 25lb dog food container with wheels where I keep my extra rolls of filament. I also put a cheap digital hygrometer in the lid. All the silica packets that come with filament go in with them.

I need to add real silica beads, just haven't done it yet.

PLA definitely goes brittle if it gets damp. I've seen entire rolls split apart from it. Supposedly PETG does too, but I've never had a problem with that. For PLA, I'll warm up my oven to 200F and then turn it off, put the rolls in there until it cools off. Seems to bring it back for a little while.

Use purple glue stick on the build surface instead of tape or leaving it bare, if you're printing on the coated surface especially if you print TPU. If TPU gets hold of the whatever that is on the build plate (buildtak?), you'll never get it off. I use window glass from the big box home store with glue stick on it.

Slypork: I'm genuinely curious, besides making figurines, artwork, knick-knacks or models, what kinds of things are people making with 3D printers at home? Do you make practical things instead of buying them at a store? As cool as the printers are, I can't think of a reason why a typical person would need one at home.


I've done a bunch of stuff with my filament printer, but it's typically in support of other hobbies & endeavors - not for it's own sake.

- parts for the robotics team I mentor
- custom stamps & tools for my wife's pottery hobby
- patterns for my metal sand casting hobby
- pieces for a CNC router I'm slowly building

I bought a resin printer last summers, but haven't done much with it yet beyond the rook and a few other things.  To many other things going on.
