Two versions Plossl - slightly smaller/quicker print for if all you use is smaller diameter plossls.

Larger - if you use bigger eye pieces, this one is 10mm larger in diameter

holes are designed for whitworth screws (camera mount/tube ring screws) or m5s will be fine

I made it in ABS, not sure I'd trust I'd trust PLA with eye pieces in case it gets knocked!

Also **the eye piece holes were designed assuming abs 1% shrinkage **
