what are the dimensions of this please?

how does the part below (above when righted) the trigger get printed with no support? just tried printing this with no adjustments and the back end is a mess....

I printed with support material. In Slic3r I set it to a rectilinear pattern with 2.5mm spacing with a 5 degree rotational offset.

Interesting idea.

Was it printed in ABS? (just guessing based on the smooth bottom)

Yes its all ABS. Heated build platform. The printrbot build platform makes the bottom really smooth.
