Calibrate & Reverse axis check 30mm

thingiverse

I'm experiencing some problems with my core XY printer, specifically a frustrating mirror image of the Y-axis on prints. Thankfully, this has only been an issue in about 10% of my prints, usually when I've forgotten to reverse the part in the slicer and end up with writing that's backwards. Fortunately, I was able to resolve this issue, so I designed this sphericube to test for any other potential problems. To minimize material usage and reduce print time, I made it hollow. You can also use it to double-check your calibration on a 30x30x30mm object.
