Derailleur hanger tool / Schaltaugenlehre

Description

This is the solution for everyone who wants to check or fix their derailleur hanger.

Model: The “Messstange” and the endcap are only required for convenience

For printing: I would recommend only printing the non-aluminum parts, and using aluminum rods and screws for the rods and Screws 

                         I used 35% Infill and 3 wall/top layers andd PLA from FILAFARM, which seems by far strong enough.

Aluminum parts: Those could be printed, however, for the proper strength and function of the build, I recommend buying them in metal, for example aluminum.

Dimensions

big rod: diameter 12mm, length about 50cm and a small partition (60mm) for inside the headpart in order to keep the crew running properly.

small/measurement rod: diameter 4mm, length about 20cm, can vary for different bicycles

small screw: M3, pretty short and only if really necessary beacuse of a lot of waer on the part it screws into.
big screw: M10, 70mm in length, m10x1 THREAD
