Ender 3 Pro bed level (hot and cold)

thingiverse

I'm looking to create a bed level test that's faster than usual so I can get it done in record time ASAP. This design is a remix of the original thing at Thingiverse: https://www.thingiverse.com/thing:3235018 It consists of two tests: hot and cold. The cold test involves heating up the bed but not the nozzle. This is because nozzles expand when heated, so running a cold bed test with it above the bed by 1mm makes more sense as a preliminary level check. In contrast, the hot test quickly heats up the bed during homing to avoid wasting any time. To keep things moving, this design is limited to just one layer.
