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.

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."

I wanted a proper home for a Waveshare 7.5" e-paper panel and a Pi Zero 2 W, so I designed this case. It’s a slanted white box with a flush wood bezel and side inlays, loosely inspired by 60s Braun gear.

* The glass is clamped by a screwed-in front mask (4 × M2), so the panel is held securely even with the bezel off.
* The bezel press-fits into the front recess. I designed for magnets, but the fit was snug enough that I didn’t use them.
* The Pi sits on a removable base and the USB cable exits through a rear notch, so the panel and Pi are easy to service.
* Two posts per side tie the frame to the body, which fixed the front corners cracking on my earlier prints.

The screen in the photos is a stats dashboard I wrote for myself. That’s not part of the listing; this is the case only, and it works with anything that drives the panel from a Pi.

I’m using these tray bins to organize all my garden irrigation fittings in an Apache 4800 case. I scaled the tray height to 54 mm and used the divider options to sort the different parts.
I’d planned to add a 12 mm plywood layer between tray levels, but found that thinner foam in the bottom and the case’s egg-crate lid foam give the trays a snug fit. The small parts stay in their compartments when I close it up.
I wanted something organized that I could take out to the garden when I’m working on irrigation and potentially leave out there without worry. This model fit the job beautifully. Thanks to the designer, Shutter_Ghost on Thingiverse!
