Remix of https://www.thingiverse.com/thing:566592 with the following improvements: One change from the previous revision (https://www.thingiverse.com/thing:566592) is that I changed the "strap slots" -- (that I actually don't use) that are intended to allow using a camera strap of some sort that can attach at each end -- to be simple rectangles. The original had triangular "tops" specifically to avoid the need for support when printing. Now that they have horizontal top surfaces, support will be generated for them. That bad part about that is that (at least for the Slic3r version I'm using) support is generated inside nearly the entire length of the internal slot made for the strap (up to the top slot) -- I didn't notice that in the code preview. Once it was printing, I figured I'd let it finish and see if the support material could be removed. It took some doing, but I found that using a hacksaw blade (which fits in the empty slot), I could successfully remove the support material.
