Makergear M2: Bridging Test Object

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

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

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

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.
