Replacement frame for MSW "Selfie" Bike Mirror

I recently crashed my bike and broke the plastic bracket for my MSW "Selfie" handlebar mirror. Typically, a bike mirror is junk after a crash because the mirror shatters. The MSW mirror is made from metal, which makes it worth salvaging.

The replacement part is designed for 3D printing, meaning that I increased the thickness of all the walls compared to the original injection-molded part. After four prototype iterations, the final replacement mirror bracket STL part should fit with all of the original MSW pieces, including the plastic handlebar mount, the metal mirror and the plastic mirror backing plate. The mirror backing plate should snap into place. I found that hot-glueing a little scrap of foam padding to the inside of the mirror backing gave the mirror a tighter fit. You might also try a little piece of double-sided foam tape.

Print instructions

I made the replacement part thicker than the original, but the mounting knob is still too fragile when printed out of PLA. ABS or PETG might work better. I had success printing a durable version of the part out of PA-CF on a Lulzbot TAZ 6 with a hardened steel nozzle.

The knob prints best with supports.
