A more useful way to calibrate your XYZ. This design has holes from 1 to 5mm, gauge blocks from 1 to 5mm, overhang and ledge from 55, 45, 35, 25 degrees. This is a really handy tool to have on your desk while designing parts to keep your scale correct.

1. Ledges/overhang: Use this to see what the print quality will look like if you have angles like these in your designs
2. Gauge Block: Use to measure gaps or maintain a scale with your models. I use it to remind myself how thick some parts need to be to be rigid.
3. Holes: Use these to get a close idea what your dimensions should be for bolts. PS: I use 2.8mm for M3 threads and 3.4mm for M3 tight through holes.
