3D Print Mechanical Parts

I see all the mechanical files are in STL format. So, it is difficult to know the hole diameter and type (drilled/tapped). Can you advise? Thanks

Hi, I just added a step file: https://github.com/CoretechR/ZeroBug/blob/main/CAD%20Files/ZeroBug.step
I used M2x6 screws for the servos in the legs (5-8mm should be OK).
To fix the bottom and top platest to the frame I used M3x5 screws (the threads go through the entire frame, so any screw length should fit).
The servo horns are screwed to the body and the legs with self tapping sheet screws (I think they are called sheet metal screws - Blechschrauben in German). These should be 2.2mm x 4.5mm or they will collide with the servo case.
You can confirm these sizes with the cad model. It's been a while so I am not 100% sure anymore.
