iOptron iPolar custom holder

This is a custom holder for the iPolar camera manufactured by iOptron. The camera is usually sold together with a holder dedicated for exact factory-made mount. But I performed a big custom equatorial fork mount, so there was no holder matching to my wedge. The camera mini-USB socket doesn't hold a cable too strong, so the cable disconnected several times during my attempts, so I decided to design the holder for the camera and the mini-USB plug.

As the camera has flat bottom surface, the holder requires a flat surface 60x50mm and around 13 degrees free of obstacles FoV. The surface must be perpendicular to the Ra axis, that's all.

Dimensions: 60.0 x 50.0 x 15.5mm.
4 holes for M3 bolts, I advise to make a thread using an M3 tap, but it's not essential.
