Lens support with aca swiss plate

thingiverse

I was looking for a lens collar for my recent purchase (Chinon 300mm f/5.6) and didnt find what I was looking for. I made this mock-up based on two other designs. The upper part is functioning as a support / cradle for the lens and the other part is the arca swiss plate itself. I used the 50mm version and extended it somewhat do the legs of the cradle fittes in the base. The lens has a filter diameter of 58mm, which gives some room but at the same time it will give support for the lens. According to Ultimaker Cura the print takes 2 hours and 33 mins.
