MiniCalTest

This is my take on the Ultimaker Mini Cal Test that they include with their printers to show the machine is working properly. I saw it in a few videos and thought it seemed like a nice little test but then searched around and couldn't find it on the entire internet. So I made an approximation of it after looking at some of the pictures and videos. Should also work as a retraction tester between the protuberances and also as a cooling test because once the upper ledge is done it will rapidly just move back and forth between the two towers and if it's all smooth until that point then cooling is likely the problem as it will go from printing them with a delay between layers to printing them in rapid succession.

Measurements to check:
Base - X28mm Y28mm
Rectangular Hole - X10mm Y10mm Z12mm
Circular Hole - D10mm Z12mm
Circular Protuberance - D10mm Z17mm from Base, Z20mm from Bottom of Tester
Hexagonal Protuberance - Flat to Flat 10mm, Z17mm from Base, Z20mm from Bottom of Tester
