52mm Gauge Pod
thingiverse
I don't presently have a need for a gauge pod, but this seemed like an interesting OpenScad exercise, so here's what I came up with. It might print as-is with powder printers, but for FDM printers you will probably need to cut it into two or more parts to prevent your slicer from adding supports. The OpenScad file is mostly parameterized, so you should be able to tweak it quite a bit with very little effort.
