Description
This is a massive object to test and calibrate your 3d printer for better overhangs with relatively flat angles. It's designed to test angles from 20° to 70° with increments of 5°. There are angle marks at the top of the object.
Instructions
Print in ABS or PLA but PLA is recommended as it has much less warping.
Update 2012-01-06: I was asked to modify the height of the object so here you have of two versions now:
overhang_test.stl -> 27 mm height
overhang_test_half.stl -> 13.5 mm height
Update 2012-02-06: I printed this thing (small version) on my new printer which is an Ultimaker. Right out of the box (Cura standard settings) it handles all overhangs very well except for last two (65 and 70 °). It's *possible* to print it, but the overhangs get "rippled".

Well, of course that depends on your printer and the software you operate it with. Some of the main settings have you already mentioned. There a lot more and you can't get around experiencing with the different settings of the software.

Love the idea, but what do I adjust to get better overhangs? Some things that come to mind are X/Y esteps, acceleration and overall print speed. Perhaps the Skeinforge guys have options that would affect this more than us Slic3r guys.

I didn't get more than 1mm up before it failed. Looks like the default of 45º is the most overhang I can do.
