Calibration Cube with Circles - 20mm

thingiverse

Calibration cubes are often printed as a diagnostic step when you're unable to print perfect circles. This version of such a test comes with indented and extruded circles built in, allowing you to streamline your troubleshooting and save time by not having to print something else with circles afterwards. Dimensions: - 20mm x 20mm x 20mm cube (+2mm to extruded circle) - 10mm indented hole diameter (2mm deep) - 10mm extruded hole diameter (8mm from inside walls) If your print comes out and isn't a perfect cube, or has messed up circles, it's likely one of the following issues: - Steps per mm are off - Belts need tightening - Z-axis is binding
