Slidr _ Print-in-place slinding card wallet

Disclaimer

This print probably won’t glide like butter straight off the bed, and that’s okay. It’s one of those “needs a little love” mechanisms. Expect some poking, fidgeting, and mild frustration at first. But if you manage to separate the parts without rage-quitting, I promise it’ll loosen up and work like a charm after a bit of use.

Tips

This print doubles as a quality check for your printer. The parts are only 0.2 mm apart, so if your settings are dialed in, they should come loose with a bit of persuasion.

Start by cleaning up the bottom with a blade, making sure all three parts are clearly separated.

Then I usually press on the bottom first to pop the inner section free, then gently (and patiently) work the mechanism until it starts to slide.

For what it's worth, I’ve been able to separate every single test print I’ve made so far. If your printer is reasonably well-tuned, you should be able to do the same.

I’ve tested the design in both PLA and PETG, and both materials work well. That said, I personally prefer PETG as it’s more durable overall, and the flexible parts tend to hold their shape better over time without loosening.

Personal tip for a smoother result

One thing that helped improve the mechanism was sliding it back and forth under a stream of water. It seems the water helps flush out tiny bits of plastic debris created by friction. Once dried, the movement felt noticeably smoother.

What I wanted to make here

Ever since I released the Sliding Wallet V2, I’ve been curious to see if a print-in-place version was possible. No assembly, just straight off the printer and (hopefully) functional.

That’s exactly what I aimed for with this design. As a bonus, I made it partially see-through using either a honeycomb or triangle pattern, so you can watch the mechanism in action. I think it gives the wallet a modern, slightly futuristic vibe and it definitely turns heads.

Enjoy :)
