Support / Bridging and Calibration Test

I needed a quick little print that I could test support settings and came up with this little test cube. You can use it to test the following:

Calibration - Finished size should be 20mm x 20mm x 20mm
Supports - Just add supports
Bridging - Don't add supports

I have put down the settings I used for one of the prints but I have used this on all my printers with various settings to get them calibrated.
