Adapter_M3_Radius gauge 1-20 mm

Hello, For the purposes of assembling the model from https://www.printables.com/model/137696-radius-gauge-1-20-mm, I created an adapter for an M3 screw, because I don't use M5 screws on a daily basis in my workshop. 

The model consists of 3 parts: 
-adapter for M3 screw head 
-sleeve fitted to the holes in the models 
-adapter for self-locking nut 

An M3x35 hexagon socket screw with a rolled head was used. It is longer than the original one from the design, but this makes the whole thing easier to assemble. I printed my models from PET-G, but the choice of material is not very important in this case. Layer height 0.1 mm.
