pcb drill 3D print model

I was looking for a drill able to make the holes of my custom PCB. This drill support is designed for a high speed motor diameter 52 mm. Since it is rather heavy, I designed carefully the vertical motion mechanism, to insure maximal alignment of the motor during drilling. Most of the non-printed parts come from a very cheap Chinese 1610 CNC. I redesigned some of them for my project. The motor can me moved first using the wheel at the back to adapt the height for a series of holes. Then, one can use the lever at the left for each drilling.
