Assembly instructions
- Install the bolt into the dry_erase_bushing block and secure from below with an M5 nut.
- Attach the dry-erase bushing block to the tool plate, securing from below with the wrist_end_cap_5mm and an M5 nut. Orient the block so the marker points forward.
- Attach the shaft collar to your dry-erase marker, approximately 8mm from the back of the marker.
- Slide the marker into the bushing block. Loop a rubber band around the back of the marker and over to one of the pegs on the side of the bushing block. Repeat with the other peg.
- The marker should now easily spring back when pushed against it. You're ready to write!
