A quick test for testing out the Z-wobble of your printer. The model prints in under 20 minutes and features a 20x20x20 mm tower out of thin walls. To help with orientation, the test has a little knob on the top in a corner, oriented towards negative X and Y (it will point towards your printer home).
I have also included the Blender file in case you want to edit it further.
