Did you ever wondered what a 3D Printer's nightmare looks like? Well, here you are the Pillar from Hell, a [relatively] quick overhang torture test.
I noticed that the standard "flat" overhang used in many test can be a little forgiving in some case, so I used a rounded edge and tiny spikes that should be harder for the printer as an overhang.
Why it's octagonal? Well, the cooling system can affects how well an overhang is printed so, doing it octagonal allows to check a lot of orientation with a single model.
Furthermore, I noticed that some overhang test can wiggle a bit during print due to the big, unsupported, curve they create. Due to the fact that each "step" of this test is indipendent, every overhang is tested alone.
To make it easy to compare 2 Pillar from Hell, I've added a little arrow on the base. By default, it should print "away from you", but you can rotate in any way you like it.
Sadly, There is no space to write the angle. For reference, the pillar start with a 40 degree angle (easy enough for…
