A quick little tool to tighten up (or remove) centrelock rotors on the trail. This has saved my butt twice already when my rotor bolt worked itself loose on long rides.

Small and lightweight (16g) it fits nicely into your framebag or emergency bicycle kit.

Inspired by an existing design “Emergency Center Lock Wrench” by RunWithScissors on Thingiverse, this is a ground up redesign that is a bit easier on the fingers, and gives more leverage. I've made the finger grips extra deep and large so you can really get in there and crank down the centrelock bolt without digging into your fingers. 

Print settings:

• 30~40% infill
• 0.2mm layer
• No supports
• No brim / no raft

If you have concerns about strength (you shouldn't - unless you have gorilla strength), you can increase # of perimeters/walls to 6.
