Test Kit

This is a simple test kit including a bed leveling test spiral, two bars for printing accuracy testing and filament temperature testing object.

The spiral:
If you have a 0.4 nozzle, the spiral will be printed with two outer shells and no infill even you select %100 or %10, pay attention for the beginning of the print to see which side squishes more and which side not touching to bed. With an adjustable bed screws, leveling is pretty easy.

The bars:
If you are printing parts to fit, you really need to know how your filament acts, how much shrinkage, which direction.. I recommend printing as high resolution as possible (0.06mm layers are fine for me)

The temp test:
Here comes the tricky part, you have to use 0.3 layer resolution and temp change every 60 layers, so for pla I begin with 215C for first 60 layers and minus 5 for the next and so. For PetG I begin with 250C

If you use cura, I couldn't find a layer dependent temperature adjustment, feel free to use other slicers.
