Yet another level test, with small circles and OpenSCAD source

Yes, yet another level test.

This does nine circles across the bed and these have circular holes in the middle (so like washers) as I find small circles one of the best tests of a level bed.

It's only a single 0.2mm layer thick, so prints very quickly. You should easily be able to see where you might need to tweak level.

Circles remove easily with a razor blade - see the EZ Snap holder on Thingiverse.
