Overhang Test

MONITOR YOUR PRINTER FOR DURATION OF TEST TO AVOID DANGER NOODLES ==================================================================== Overhang angle test. I couldn't find one that was literally just for overhang angles and avoided embedded numbers which can skew results, so I made a couple with Blender. Stupidly simple. Base is 2mm tall and much wider than the arc to prevent any cantilever forces from tipping it over. Segmented in 10 degree increments. `Overhang Test 5.stl` tests angles at 5, 15, 25, etc. up to 85, while `Overhang Test 10.stl` tests angles at 0, 10, 20, etc. up to 90 With 0.2mm layer heights, Z height breakdowns are approximately as follows: `Overhang Test 5.stl` - 5 degrees: 2mm to 10.6mm - 15 degrees: 10.8mm to 18.8mm - 25 degrees: 19.0mm to 26.0mm - 35 degrees: 26.2mm to 33.0mm - 45 degrees: 33.2mm to 38.8mm - 55 degrees: 39.0mm to 43.6mm - 65 degrees: 43.8mm to 47.2mm - 75 degrees: 47.4mm to 49.4mm - 85 degrees: 49.6mm and up `Overhang Test 10.stl` - 0 degrees: 2mm to 10.6mm - 10 degrees: 10.8mm to 19.0mm - 20 degrees: 19.2mm to 27.0mm - 30 degrees: 27.2mm to 34.0mm - 40 degrees: 34.2mm to 40.4mm - 50 degrees: 40.6mm to 45.8mm - 60 degrees: 46.0mm to 49.8mm - 70 degrees: 50.0mm to 52.8mm - 80 degrees: 53.0mm to 54.2mm - 90 degrees: 54.4mm and up If you think your printer can hit 70 degrees, you'll want to crank the the perimeters and shells up to the max to prove it. If not, 5 perimeters and 5 shells should be more than fine. I do not know if orientation plays a role for bedslingers, however I assume the arc being in line with the Y axis would minimize bed movement. That said, it also highly depends on your part fan orientation -- one-sided fans might need to flip the arc with the "outside" facing the part fan for more accurate results. Try a few and see what happens!
