When assembling and disassembling my Cetus 3D Print I found it oftentimes hard to recalibrate the Y-arm in the Z-direction. This is why I designed these stands. You will need to print them twice
To use them perform the following steps: - Turn off power - Remove extruder assembly - Put the build plate in the middle of the x-axis - loosen the bolts of the Y-arm (optionally also from the linear rail) - Fix the stands to the arm and place at the far edges. - Make sure that the stands rest firmly on the build plate - Fasten all the bolts.
