I got tired of printing the same boring old bed level tests while calibrating my various printers so I designed one that was at least somewhat fun/interesting to make!

It measures 212.4 x 212.4 at a single .2mm layer height because I wanted it to be usable on most beds. Any other settings are up to you. I included a sizeable tab on the bottom right corner for easy removal from the print surface. I've found that it is also handy as a rough test for bed adhesion as well, due to the number of acute angles in the model.

The included image is using a dual color matte filament from Polymaker that gives it an interesting three dimensional look.
