Minimum Viable Feature Test for walls and posts designed for 0.3mm layer thickness and 0.5mm
extrusion width. (These are good standard settings for a 0.4 or 0.35mm nozzle.) Features are in
0.5mm wall thickness or diameter increments to match the extrusion width. Sets are in full 0.3mm
layer increments in the following heights: 0.3mm (1 layer), 1.2mm (4 ly), 2.4mm (8 ly), 3.6mm
(12 ly), 4.8mm (16 ly) and 9.9mm (33 ly).

The opposite side has a 70mm ruler in 1mm steps for reference.

This test part is a handy physical design reference to know what feature sizes work at different
heights. I keep it on hand when I'm working on a design for 3D printing.

If you print one please consider posting a Make with the printer and slicer details. Hope you find it useful!
