Calibration fidget cube

Hi guys,

the basic idea behind this was to encorporate more tests into dimensions test cube and make improvements to it. So here's what I came up with:

• dimension and clearance test in one print
• 25 mm test cube instead of standard 20 mm so the measuring device tolerance plays lesser of a role
• clearances from 0.2 mm to 0.6 mm
• each cube has clearance marking on the bottom
• cube is hollowed out for faster printing with wall thickness of 0.9 mm and can be printed with under 3 meters of filament
• 3D printing optimized, no supports required
• chamfered edges - squished first layer can't throw your measurements off now
• after you are succesfully done it turns into fidget spinner

As standard .3mf, .stl, .step and .obj files available!

UPDATE (28.5. 2022)

• added full, not hollow version
