Cover for Pinion C-Line Bicycle Gearbox

thingiverse

The Pinion C-Line C1.12 gearbox has its change mechanism shielded by a plastic cover. When used on a mountain bike, it's prone to vanishing acts. Here is a replacement part that can be easily made at home. I highly recommend printing this design with the build plate aligned vertically (with support) so that the layer boundaries intersect the tabs at an angle. An alternative version has also been included for printing with the face down orientation; however, it's worth noting that the tabs may break off if printed in this manner.
