Tool for leveling Ender 3 bed

Made by a slowpoke for other slowpokes.

Prints a maximum sized skirt (watch those clips) in 10 rounds, pausing on each lap for adjustments. I recommend tramming with a piece of paper to rough in the level first. When the print pauses, adjust only the worst corner as it will affect the others. After 10 laps, it will print 9 circles for gauging.

Based on 9dot stl by FurioPrints
gcode has the skirt and pauses.
