The file '30mm To 20mm Telescope Lens Adapter 3D Printer Model' is (scad,stl) file type, size is 144.2KB.
I bought some 30mm lens... And I have a 20mm telescope!
So here's an adapter.
Best printed with a bright color so you don't loose it if it falls on the grass in the dark when stargazing outside.
Works nice for entry-level telescopes, but may probably be inaccurate for 500$+ ones.
Works well with my ~80€ Buki Telescope
