Hartmann mask for SVBONY165 30mm

This is a Hartmann-mask for focussing with a SVBONY 165 30/120mm Guidescope. A Bahtinov-mask did not work so I designed this one.

I DID NOT TEST IT ON A STAR due to cloudy nights...

So print on your own risk.

I used FUSION360 for the design.
Material is PLA+ black pronted on a an Ender 3 S1 PRO (0,16mm layer 60mm/s)
