Space Team's µHoubolt CAD Files, SolidWorks & Step
Now with actually useful STEP files! And FreeCAD .FCStd as an extra. Mostly done, tell me in "Issues" if anything is missing. Any help from folks with access to SolidWorks is very much appreciated.
Extracting parts and assemblies with VariCAD. VariCAD opens the uHoubolt.step without any issue, by a miracle of Dark Sun Gwyndolin or other deity.
How did I obtained VariCAD? I prefer not to say, but it was the only choice.
Electronic circuits with a lot of small parts cause extremely large file sizes, so files without electronics are included. Large files can freeze or crash CAD programs.
Lesson learned: use OS software to design OS hardware.
