Printed spacers were installed. The fit on all of them was very good. Uninstalling the bolts was easy but the number of bolts which carefully held everything in place was unwieldy. Someone trying to replicate this project would have to be careful to align everything but having the spacers included with the pieces takes away the guess work. Next step will be to include the spacers right on the pieces so they will print as a single unit which will eliminate having to understand where each spacer goes, it will simply be a matter of aligning the four wrist-mounting pieces together.
