Custom cable ducts and skirts

I scrapped the OpenSCAD cable duct idea mainly because it couldn’t export to STEP (totally not because I didn’t want to learn it for 10 hours). Instead, I just redesigned them from scratch in OnShape and made sure to use its configuration features so I can generate different lengths and bends. The hardest part was figuring out how to mount them to the DIN rails in a customizable way. I realized that it was dependent on the spacing of the rails, and I somehow made mine a perfect multiple of 35mm which is exactly what DIN rails use. So I have a grid of holes space 17.5mm (35/2) apart which lets me screw in DIN clips anywhere along the duct. I’ll publish these at some point because they’re pretty useful. I do want to make them configurable outside of OnShape though, so I’ll port them to build123d soon™. I also printed a small version of them to test the snap fit for the cover (it’s perfect).

After that, I started getting the whole layout setup for the electronics. I then moved on to finishing up the skirts and adding mounts for the power plug, switch, fans, and motor drivers. This was surprisingly hard since I had to make cuts across pieces of the skirt. The under-bed electronics design is mostly done now with the exception of the screen (I need to make a case/mount for it on the front of the machine).

While it’s not in CAD because STEP files aren’t provided, there will be a handful of WAGO connectors to split power among components.
