Dual Stepper Bracket

thingiverse

To resolve space issues in my homemade 3D printer chassis, I utilized stepper driver brackets that reduced the needed area by half compared to single PCB-mounted stepper drivers. Vertically mounting four stepper PCBs required less room than a horizontally mounted card. Printing large objects necessitated a heated build platform for optimal results, but rafts could also be used on unheated platforms. I applied .3 INFILL in SkeinForge and activated COMB to minimize plastic strings between the four bracket-mounting posts. The mounting hole spacing allowed custom PCB orientation. Photos demonstrated how Gen 3 stepper driver PCBs were mounted using M3 x 35mm screws and nuts, while M3 x 8mm screws could individually secure each PCB to the bracket. A 7/8-inch (22mm) spacer between hole pairs could be added for increased bracket strength when using M3 x 35mm screws. The bracket itself attached to the chassis with two M3 x 12mm screws and nuts, and it was compatible with both Gen 3 and Gen 4 drivers.
