About this 3D model

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/hlSHyKI2T9e I reworked this part to reinforce the nut location. The original part seemed to me too fragile and i broke both of my motor gears because of that. With this part you should not break it while screwing the scren inside the nut!
