I want a case for my Pico project, which is basically a Pico with a small level-shifter chip.
It needs a hole in the case for the USB micro port on the Pico, and it needs a hole for some sort of plug to connect to the NeoPixel lights. Also I’d want a tiny hole to stick a paperclip in, to get to the SelBoot button.
The only way I can think of is to 3d print something. I have a friend with a 3d printer, but what I don’t have is a design. So I want an app to design a 3d printed case for a Pico, plus some other bits. And I have a Mac, so it can’t be Windows-only (or Linux-only).
Design / CAD
FreeCAD
Well worth trying
Onshape
Browser-based. Built for mechanical design. Free for public files.
Autodesk Fusion
autodesk.com/au/products/fusion-360 and search for “Personal Use”
Professional grade software, but “Limited Use version” has limited import/export file types
Shapr3D
Smooth, modern, built for mac. But paid subscription required for advanced features / high-res
Tinkercad
Web-only. Only for beginners? Too simple?
Blendr
Mostly for organic / artistic shapes. For sculpting, not CAD.
Slicing
Cura
ultimaker.com/software/ultimaker-cura
Long history as stable & reliable. Supports almost all printers on the market.
Orca Slicer
Newer, beinner-friendly but advanced slicing features. Fork of Bambu, brings Bambu features to other printers. Supports Bambu and Prusa printers, and others (including the one I care about).
