Wanted a minimalist way to display my CDs, so I designed this super quick print.

• Print time: < 30 mins
• Filament: < 10g
• Mounting: 2 nails or screws

What do you think?

I’ve been working on a custom trading card storage drawer designed specifically for the IKEA KALLAX shelf with bottle insert.
A few features of the design:
Holds up to 800 trading cards

Has a front slot for a sleeved card, so you can easily identify what’s inside each drawer

Uses a two-piece design to make printing possible on most consumer 3D printers

Designed with trading card collectors in mind

The idea is to make a KALLAX setup more practical for organizing a collection while letting you use a card on the front as a visual label.

I’d love to hear what you think! Is this something you’d use for your collection? Any features you’d want to see added or improved?

Sometimes you don't need all of the bottle or pacifier inserts that come with the Momcozy KleanPal Pro bottle washer. This print provides a convenient, off-the-counter place to store these accessories while still keeping them organized!

Simply attach with command strips to either of the sides. The accessories fit nicely into the slots without being too tight.

The bottle washer can get warm during the washing, steam, and drying cycles. I printed this out of ASA for better heat resistance. I've also provided a PLA profile, but I haven't tested PLA – it's possible that it could warp due to the heat. PETG or ABS could be used instead of ASA.

I made this because I wanted to print something and clean up the counter, and surprisingly my wife approved of it with no convincing!

Model available on Printables. It's parametric*, so you should be able customise to whatever coins you need (although I'm sure there are new and creative ways to break the model). I use the EUR and CZK versions, but I included some best-effort models for other currencies too (I included the measurements on the page if you want to verify them).

*I should note I have no idea what I am doing, I'm self-taught

I designed this helper tool (OmniGrip) for people with arthritis, tremors, or limited hand strength who struggle with the painful pinch-and-twist motion needed to turn a key.

Most printable key turners rely on fixed, narrow slots that only fit standard flat house keys meaning anything with a thick plastic head or an odd shape just won't work. On top of that, swapping keys on them can be a pain if your fingers don't work great.

Instead of a rigid slot, I used a bed of flexible TPU 95A pins inside a rigid outer shell. When you push any key down into it, the pins bend out of the way and lock around the profile with a lot of friction. No fiddling or setup needed just press it in and turn.

A few quick design details:

\- The outer handle has 5 rounded lobes so you can turn it using your whole palm or knuckles instead of a tight pinch grip.

\- The TPU insert locks into the rigid shell with a 10-tooth spline inside, so it won't spin freely when you apply torque.

\- There's an ejection hole at the bottom: if the TPU ever wears out, you can just push it out with a pencil and print a new 15g core instead of wasting the whole shell.

\- As a side bonus, it works great on a desk as a pen/stylus stand so you can grab things with a full fist instead of trying to pinch them flat off the table.

Modeled parametrically in OpenSCAD so dimensions can be tweaked if needed.

Feedback and suggestions are very welcome!

The main difference between my customiser and others out there is I have pre-set dimensions for popular boards to make it easier to just pick your board and style.

I do need help making sure I have dimensions for all the boards people want, though, there are a lot of variations and clones out there!

I know it probably has a name, but that's neither here nor there.
Edit: Looks like it may be a type of spanner nut

Needed to remove this nut from a telescope motor so I can measure the gear (my calipers don't reach into the bowl far enough).

Third iteration fit (couldn't accurately measure the nut either XD) and with a few picture hanging nails heat set I got it out.

Now to learn how to design a gear!

Broke my sharp vacuum canister when trying to clean out a horrific smell that turned out to be the neoprene washer between the top and bottom sections. The first model didn't have enough airflow indicated by the sound of the vacuum. Modelled in onshape, printed on a p1s. Saved me ~$40 for a replacement canister.

I printed a simple cover for my bottle warmer since it doesn’t come with one. It helps keep dust out of the water when I’m not using it, might help reduce heat loss while it’s warming up, and gives me a spot to put a few things on top when the warmer isn’t in use.

Nothing fancy, just a little practical thing I wanted for my own kitchen. Figured I’d share it in case anyone else finds it useful!

I’ve uploaded the model to MakerWorld if anyone wants to check it out.

There are nice tent stake pushers and cleaners for things like the MSR Groundhogs, but somehow none seemed to exist for the stakes that came with my Copper Spur!

I made this to both act as a pusher and cleaner in one lightweight (1.5 gram) part.

Feel free to test it for yourself!

Just made my newest model and am super proud of it.
Psyduck Controller Holder

Didn’t love the prices and features of available featherboards so I designed and printed my own. 3/8” nuts thread on to 3/8” bolts locking the body into place on the table saw. I designed handles for the nuts for ease of use. The featherboard slides into a 3/4” channel but can be customized to fit into any size channel. The feathered piece is also removable from the body, in case feathers break they can be replaced without re-printing the body.

If anyone would like I can post more videos of it in action or how it works/is assembled. I can also post STLs if anyone is interested. I printed this using PET-G, it cost about $2 in filament and has lasted 4 weeks of heavy use.

P.S. I originally posted this in r/woodworking and was asked to repost here. I am working on setting up a GitHub to share the STLs!

After many failed attempts, I managed to create a rewritable notebook page that doesn't snap along the lines. It is just 0.24mm thick and can be folded repeatedly without breaking. I know it might seem like a trivial thing—just a simple sheet of paper—but it’s not. To create it, I had to make a three-layer sandwich. The middle layer provides the structural integrity; this way, there are no weak points in the sheet, and flexibility is guaranteed.

You can view all the tests performed via the project link. I hope it proves useful to someone as a notebook-style "erasable board."
