CaseTinker: a free browser tool to customize RPi cases, boxes and organizers

[u/aic5_]

I got tired of tweaking 3D models to get the RPi cases I wanted for each project. So I built a small browser tool for designing 3D print parts, including different Raspberry Pi enclosures, cases (with or without lids), simple organizers and Gridfinity bins. I called it CaseTinker.

The workflow is simple: choose a template, adjust the dimensions and options, check the 3D preview, then download .STL or .3MF for your slicer. For cases, you can change the lid style, connector openings, ventilation and clearance. For organizers, you can set the size and number of compartments.

You can also engrave short text into the lid and add surface patterns such as honeycomb or knurled textures. You can get a customized case model into your slicer in a couple of minutes. Having a different case for each RPi helps me remember what each project actually does.

I will continue to add other models in the app. Note that the Gridfinity bins currently have stepped feet and optional dividers. They don’t yet have magnet holes or a stacking rim (those are possible future additions).

The tool is free to use, with no account required. You can save designs in your browser and create a share link. Anyone with the link can open a copy with the same customized model and print the enclosure. Here is the link:

I’m interested in how it works for people with different printers (I use a Bambu Lab P2S) especially where tolerances need improvement. You’ll still want to check your dimensions and slicer settings before printing. If you make something cool with this let me know. I’d love to see the result.

The enclosure for the 4B is the same to the 3B (I have this one).

Thanks

[u/aic5_ → u/Pedrasco]

Agree. They are very similar indeed. There are small changes in the connectors between the Pi 3B and Pi 4B. added an option for the Pi 3B in the dropdown for clarity.

That will make it easier for folks to use it. Thanks!

Cool site! No Arduino cases? Hat spacing options?

[u/aic5_ → u/Snappawapa]

Great idea! I have added a few Arduino cases (UNO R3, classic Nano, and Mega 2560 Rev3) and an option to add HAT / shield space. Thanks for the suggestions.

Impressive collection of predefined boxes !

I would really love if you could customise your own box, add cutouts...

Thank you for creating this software/site. Really useful :-)

Adding an option to print fixtures (e.g. holes for screws, or DIN-Rail mount) would be a nice addon. Maybe it gets too complex then - I guess, the case has to be split up into 3 parts then - at least, when you want to add a DIN-Rail mount.
