This model is not currently offered as a verified ready to buy print.
What it does
- Works with your torque wrench so you can tighten the brake nut safely to exactly 40 Nm
- Includes both square and hexagon fittings, so you have backup options when one shape isn't enough
- Prints in ASA at 80% infill for strength that holds up under real torque pressure
- Hexagon design fits a standard 32mm nut, so you can use tools you already own
You can service your own Shimano disc brakes without paying a shop, when you have the right tool. This 3D-printable tool grabs your brake rotor locknut from both angles, so you have choices when you need them.
The square opening handles basic jobs, but when you need serious torque, the hexagon lets you attach a 32mm wrench or nut to your torque wrench. One maker tested this design at 40 Nm using ASA plastic and 80% infill. It survived both tightening and loosening. You get a tool built to the exact specs your brakes require.
Print this yourself and keep it in your workbench. No waiting for shipping. No tool rental fees. Just you, your printer, and the brake work you need to do.

Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
