Calibration Cube&Circle 10mm and 20mm Version

October 20th 2017: New Version available with bridge - https://www.thingiverse.com/thing:2596024

October 28th 2016: Updated with the 20mm Version for easier print with bigger nozzle diameter

This is my customized calibration model. Prints quick and does not require a lot of filament. You can find the dimensions on the attached picture in mm. There is also a Sketchup file attached in case you want to adapt it to your needs.

Happy calibrating....
