We're excited and proud to launch Thingiverse Apps. Learn More about what this means to you.
Rostock is a delta robot 3D printer.
This part is the bottom bracket that holds a NEMA17 stepper motor, a pair of 8mm smooth rods and a plywood board.
Newer versions of the OpenSCAD source files will be published here: https://github.com/jcrocholl/rostock
Print three of these and install them at 120 degree angles on a plywood rectangle of 300x350 mm, with two corners cut off diagonally. The plywood mounting holes are sized to work with #11 wood screws or M4 screws, no nuts needed.
Clamp the smooth rod with 16mm M3 screws, washer on the outside, hex nut on the inside. Stainless steel fasteners are recommended.
