Flexible Couplings

Mix and match any combination of these 8 mm and 5 mm diameter couplings. The 5 mm couplings have both round bore and D-shape profiles.

Adding a spacer between the couplings increases flexibility. Any type of spacer should work (washers, nuts, standoffs, etc.) I include a spacer with an outside diameter of 36 mm x 2 mm thick. It could be scaled in the Z direction to adjust the thickness. The bolt circle diameter is 24 mm if you want to mate these to one of your own designs. It is designe
