When building cages for rabbits out of various forms of wire mesh, you often find a need for raising the mesh slightly off the surface.
My wife, Debbie Campbell, came up with the idea of these little standoffs to
make cleaning the bunny areas a little easier.
UPDATE: I reorganized these old scad files into a much cleaner implementation that uses one scad file to generate the two STL files.
Print one corner piece for each corner you need to support. Print the straight pieces for long runs or for corners that are part of doors.
