Shimano Cantilever Brake Repair Sleeve

thingiverse

On my old 90's mountain bike... the little plastic sleeve that goes around the mount for the brake cantilever cracks over time. The repair parts used to be available. So you must decide if you want to replace the entire brake system on an old bike. OOOOR you could just print this.... So I made this "sleeve" that goes over the cracked piece. There's two versions one with an adjustment screw cutout and one without. Printed 100% solid in PETG.. it should be a tight fit over the top of the cracked piece. This is stupid-simple solution. It works and the print is easy. I think there are complete printable 3d replacements but Im not sure I believe that I can print a part with strength with all the load bearing holes in it... so this is a reinforcement of what's already there.
