I’ve finalised the design but as expected the quotes are huge and not worth getting a one-off made really. CNC before anodising is £255, resin 3D printing is over £150 for a decent resolution.
Normal filament printing is realistic at about £20 but it will look rough.
I’m going to just go with wood I think, stained black. For the window I’ve found a perspex disc with a rubber traction ring around the outside to fit into the hole (hence the unusual dimension in the middle).
