UFO Disc Golf Mini Marker

The original diameter I made is 135mm. I've reprinted mine at 75% to make it more pocket-able close to 100mm. I suggest using silver metallic filament and concentric top layers.

Light sanding the edges of the windows might be necessary for good fit. And some glue.

Might also have to reorient the window in Cura to print it flat and print 6 of them.
