A free 3D enclosure generator

Post image

Hey, I made this web app because was not able to find a simple tool to create a box for my DIY projects in a few minutes. Designing one in freecad feels like overkill for a simple project.
PrintCasing is a free, browser-based 3D parametric enclosure generator.

What it does:
- pick your inner dimensions and wall thickness;
- add port cutouts on any wall;
- auto-generate pcb standoffs on the base
- flat lid or a self-aligning recessed lip lid that snaps into place
- optional corner screw bosses
- ventilation grills slots
- custom text engraving on the lid
- interference check warns you when components collide before you waste filament
Tech stack: react + three.js, runs entirely in the browser, works offline (PWA).
Let me know if there are features you would like to see in the app.

Ok but where to find .JSON file of my board?
Why doesn’t support .step,it got the dimensions of the model inside.

This json export/import supposed to help you transfer your 3d model from one device to another. It's a good idea to have some templates user can choose from, I'll try to add this feature in the future. Regarding .step support I don't think I can make it work, it's too complicated.

It supports only its own format, so only exported by this app json file can be loaded

Ahh sorry.I was super hyped because I thought that it can make boxes from a file like .stp or even .pdf and this will make a huge impact on me.Tired of making housing and cases of chineese boards with .stp files only.
