Squareness and dimensions test

I wanted to test how square my printer actually prints and how the dimensions are accurate. Also I didn't think that printing 20*20 mm cube will really show how square it is and scaling it up would take just too much time and material.

That's why I made this pyramid where you have 90 degree angle between each axis and the main sides are 100 mm long. Being this big you can see much better if you print square and it still prints pretty quick.

Also as you can see in the pictures I found that my Z axis lead screws are making inconsistency in the print (as there are 12.5 repeated “waves” for the height of the print which means 8mm height of each one so per every rotation of the lead screw). End the edges would also need some fine-tuning. At least dimensions are fine and the angles as well.

To print fast (around 1 hour) print 0 infill, 2 perimeters, 2 bottom layers, layer height 0.24 and I cranked up speed to 200%.
