Fun with kicad 3d

I have been getting more interested in using kicad’s 3d capability. Last year I was learning v6 but concentrating on building my symbol and footprint libraries – I did a few 3d renders of boards, but it was mostly for novelty.

This year with v7 I have been refining my libraries and filling in a bunch of missing 3d models, and I wanted to make a little board for testing 3d export. Instead of making a pcb to fit into an enclosure from hammond or new age, this time I wanted to make the enclosure to fit the pcb.

My test board is just a gizmo for adapting jtag/swd/tagconnect programming cables. The only design constraints I imposed was to use a single screw hole and to use rounded pcb corners for fitting in a filleted case. Kicad render:

I exported it from kicad as a step file and saved it as stl. Then, since I didn’t yet have a pcb from fab to proto with, I printed it so I can test fit it in my new case:



And then I could put my kicad “board” in for a test fit :slight_smile:


And a follow-up after getting my board – and a refined case that (unintentionally) kinda looks like one of my old teletype machines:


so, you should be able now to import back (eg: as a STEP) the case into KiCad 3D-Viewer :wink:
