About this 3D model

A thing to debug my printerbot's bridging problems. A variety of shapes on two different layers - otherwise it tries bridging the whole thing in one go. Printing this has been somewhat enlightening. There seems to be a problem bridging to a single layer wall. Bridgetest2.stl has several wall thickness and heights. The bridges are all at the same height and Slic3r spans the lot in one pass. If you have a gcode viewer such as the one in repetier it can be interesting to see what the slicer does.
