Shimano I-spec B to bar clamp shifter adapter

thingiverse

Designed to use I-spec B shifters without I-spec brakes. Mounts directly to the handlebar. Needs 3 m3 nuts and 3 m3 bolts. I used a pice of old inner tube between the clamp and handlebar, to increase friction and reduce the torque needed, so the plastic joints are under less stress. Printed it inPLA and 0.18 layer height. ABS would probably be a better choice. Have more than 100Km on them and they still work correctly.
