Macro ring/tunnel

Macro ring/tunnel meant for microscope lenses.

The led used is: https://www.aliexpress.com/item/1005003443374613.html, 12V 4000K led ring.

The cover part can be any color, but I prefer it black. The transparent diffuser could work also in white filament, but the transmitted light amount would be smaller.

I tested it without sanding the transparent part, but sanding it would probably give better results.

0.3mm layer, no supports needed.
