But why 20mm? Personally I use a 10 and a 5mm cube when i calibrate the printer at the maker space... But my digital callipers are accurate to 0.005 mm, so I can detect a tiny error even at 10mm

How this cube help me to test my printer?

the cube is supposed to be a 20mm cube. So, if you print it and you measure the cube in all directions, you can find any kind of error in the resulting size. One common problem is the "steps per mm" setting in the firmware. If you cube only measured 19 mm in the x axis direction, then it could be an issue of your "steps per mm" being off. If you divide 20mm (desired)/19mm (actual) you'll get a correction factor! So all you have to do is multiply your current setting by (20/19).

Print and repeat!

Da Vinci 1.0 printed great! thx!

I officially hate this thing. If I had nickel for everyone I printed... I'd probably have around $5
