Simple printer calibration models

thingiverse

I have an Overlord Pro printer which has a lot of issues. I searched Thingiverse for a usable test model set. Finally I have found one but the files in it was completely unusable. I get the model measures and remodelled them in OpenSCAD. Since the idea is not mine I share all the files here. Happy calibration! EDIT: Added cylinder and wall tests as well. Corrected cylinder walls (were half of the desired thickness). V2.1 Added tall and wide blocks and cylinders. Print them with RAFT. After a big repairing of my printer I started to calibrate it again. The bed leveling is good, the external sizes are acceptable an every directions. The holes are too tight. Stringing is very strong. Some ringing and pillowing can be seen. I had a lot of things to do but the calibration model did a good job ;-)
