Gearbox rate 4:1 with 3d printed pieces. Assembly. The motor shaft length for nema 23 model 23HS5628 is 27.5mm from front motor cover to the shaft end. The pieces that we need are: 1 piece 56.5mm x 6mm of diameter shaft, this is easy to get in aliexpress. 1 nut of 1/4 in, we need modify the center hole to 6mm. 3 pieces 1/8 in set screw to hold the shaft. 1 piece 1/8 thread tap drill. 4 pieces bolt 4 mm x 40 mm. 4 pieces bolt 4mm x 25mm. 4 pieces nut 4mm. 1 piece pession collar (inner diameter of 5mm). 1 piece 1mm flat washer.
