Printer progress. Design is a little weird since I'm working around the aluminum extrusion I'd already bought. Smooth rods would make more sense. Should work though. Pink bits still need work to mount the motors, which will probably need to be inverted. I also need to throw together the bushings. Green bits are ready for test printing. Screw count for the x/y bits seen here should be a maximum of 14: 3x per motor to mount the drive spools from Richrap's sli3dr printer linked above, and 4x per motor to attach to the frame. The dollo printer bits I'm using as a library have worked well in the small test pieces I've made.
