A lens grinding die for experimental 3D printed lenses

I have made this as a hand grinding die for a Plano-concave optical element. The goal is to ultimately create a meniscus lens capable of producing 4×5 photographs.

There is an internal manifold for supplying water during the grinding process. It may end up being further modified with grooves in the grinding surface for slurry clearing.

When slicing, I chose Thick walls, (3mm) as this grinding die will itself be polished by the grinding process.

Designed and oriented for printing with touching build plate supports.
