The New Hotness

The overhang quality is on the low side of OK, but that’s without any particular configuration tweaking:

M2 - Overhang test - overhang view — M2 – Overhang test – overhang view

A few strands didn’t quite anchor to the far side of the overhang opening and hang down inside:

M2 - Overhang test - overhang detail — M2 – Overhang test – overhang detail

Curiously, the slab on the other side transitioned from the usual 0.10 honeycomb fill to completely solid about half way up:

M2 - Overhang test - slab view — M2 – Overhang test – slab view

As with all the other objects, there’s no stringing or oozing. Looks good to me!

The slic3r configuration, which doesn’t show the bridge speed of 100 mm/s:

The OpenSCAD source came directly from Starno’s object on Thingiverse.
