As the RepRap build continues, I designed some motor mounts that will work with the 40mm extrusion I’m using. The Nema 17 stepper motors I’m using are about 43mm wide, so they hang just outside the extrusion if centered, so I’ve designed the mount to be slightly off-center so the motor do not hang outside the frame.

I’ve incorporated the model into the overall render of the printer. I don’t have the hole yet for the smooth rod to fit into the mount. I’m looking at models like this one to base my work on.

I’ve also worked on the full model a bit, and made it slightly larger for reasons I’ll get into in a future post. I’m currently thinking of a few ways to make this machine a bit more flexible in its capabilities, and a larger frame made sense for that. (And it means I can waste less extrusion when I cut it down to size.)

Things look wonky in this photo because that’s actually a piece of 38mm (?) extrusion I had handy, since all the 40mm is at Milwaukee Makerspace right now. I’ve got a few projects to wrap up before we cut down and mill the extrusion, so I’ll probably keep working on the printed parts for a bit.
