Leica R to 2inch

My father showed me how to process black and white film, when I was 10. Since then, it is something I have been coming back to several times in my life. Now, with a shock wave of ai-generated mumbo zambo coming our way, it is time again to go analog. 

My goal for the coming stargazing season is to see how far I can push film-based astrophotography. (Pun intended).  I took my father's Leica R6, a camera from the 90s that runs entirely without batteries, and ordered a pack Ilford Delta 3200. Unfortunately, I couldn't find any product or a 3D model to connect telescopes (or anything else) to Leica R camera bodies.

So I pulled the calipers and made one myself. This adapter provides a lense-side R bajonet and a 2 inch tube, which is a standard interface for visual astronomy and astrophotography. 

Print instruction: 

The tiniest movement can distort the image, therefore a stiff material is important with excellent dimensional stability. I used ASA-CF. PETG-CF should also be good, or PLA, if in Leica Red.

The model uses the principle of over-sizing to achieve stability. Walls of 1.2mm and 40% infill give a good balance of stability and weight.

The model is optimized for printing  with the 2 inch side on bottom, although it can be printed either way. Support (on objects!) must be enabled for the bajonet side, but very little material is actually used.

In remembrance WOS.
