Crayford Focuser Adapter for Hadley / Metric

As a beginner, it was difficult for me to work with a self-printed focuser. I therefore designed an adapter for a Crayford 1.25 inch focuser, which can be bought on Aliexpress or Amazon.

The adapter can be installed instead of the self-printed focuser on the original Hadley - UTA, you don't have to disassemble the telescope. It was important to me to be able to switch between the different focusers. M4 screws and nuts were used.

Adapter to Hadley - 4 x M4 25 mm
Crayford to Adapter - 4 x M4 20mm

The adapter works perfect, if somebody needs an imperial version please let me know.
