Generic telescopic mudguard for bike, you have to design your own mechanical adapter to match your bike topology, using the “M3_screw_inserts_Dimensions.png” screenshot
The inserts I used are brass nuts, hot insertion M3 X D4.6 X L3.0
If you are a FreeCAD user, you can download and modify my project, I made a parametric design
Enjoy,
The author marked this model as their own original creation.
