Disc Rotor Truing Tool for Park Tool truing stand DT-3

thingiverse

A cheap alternative to the rather expensive Part Tool DT-3. You just need two M6 hex screws. One about 100 mm and the other about 70 mm. You can also just shorten a screw to get to the desired size. I needed to use a thread cutter to remove the friction from the integrated thread. You can also scale it up just one or two percent if you don't have a thread cutter. The tool works perfectly for me and saves a lot of money if you're not a professional using it on a day to day basis. PLA is good enough as material, you don't need anything fancy.
