Shimano Disc Brake Spacer

thingiverse

I have created exact replicas of the original Shimano spacers designed specifically for four-piston brakes like the Saint and Zee. These spacers serve as a critical backup when the wheel has been removed from the bike. Initially, I encountered difficulties obtaining a smooth surface on the bottom of the spacer, so I designed a second version optimized for 3D printing. While material choice shouldn't impact performance, I've used ABS plastic for my replicas. To ensure better bed adhesion with ABS, I employed a Raft in the design, but if you're using an enclosed printer or printing with PLA, you won't need one.
