Hi,

I made these 3D blocks for testing the accuracy on my 3D printer. The idea is to print all the parts using your prefered settings on your 3D printer. After the parts are printed you simply place one block after the other in the block with the cutout and then see what block that fits.

Example: If the 7mm and 6.8mm blocks dont fit, but the 6.6mm block fits just perfect. You then now that your printer (with your settings) adds 0.4mm "too much" to the parts (that is 0.2mm on each side).

The number on the blocks is the width on both sides. The hight is 7mm and the text is 2mm deep.
