Square Plumb Level

thingiverse

It's more suitable for educational materials or symbolic purposes rather than precise measurements. To achieve better accuracy, a larger, heavier plumb bob with well-designed parts is required. Nevertheless, this tool can still measure gravity direction, 90-degree angles, and levels for most basic tasks. For a more substantial plumb bob, you can attach a 22 mm steel ball holder to the print and place a 22 mm steel ball on it. Alternatively, you can create the plumb with a 100% infill ratio.
