Axis housing drilling

3.3mm holes for M4 threads. The axis adapter was turned on a lathe, it adapts the 4mm focuser shaft to 6mm motor output shaft. M4 tapped holes for set-screws are on the side.

The focuser shaft is 4mm only for the first 10 mm of the 15mm deep cavity, so the adapter has a 6mm inner diamater in that end for the first few millimeters as well.
