1 1/2 inch PVC Pipe Sanding Tool

I needed a way to sand some 1 1/2" to 2" PVC pipe adapters down a bit using a power drill, and this is what I came up with.  Since I made mine, I redesigned it to use different size nuts and bolts, including 1/4"-20 and 3/8"-16 for the SAE folks (God bless em), and 5mm x 0.8mm and 8mm x 1.25mm for the Metric crowd.  If you need to use 1/4"-20 or  5mm x 0.8mm hardware, try the models with “M5” in the name, they use a smaller diameter hole.

This design has internal bolsters to allow printing with normal infill, though it may be a good idea to use 3 walls if you need this to last a while and are using larger hardware.  I printed mine with a 0.6mm nozzle, if you are using a smaller nozzle, you may need more walls.

The pic shows how I used it, minus showing it chucked in the drill.  To clarify though, I chucked the bolt end into my drill and used the drill to spin the tool (and the pipe fitting), which allowed me to sand the OD down just a tad to get the adapters to fit a slightly out of spec 2" coupler on an ABS valve body.  I don't really expect this to be much needed by other folks but thought, “why not post it anyway”, so that's what I did.  Hope somebody finds it useful.  

If you make and/or use this, it's at your own risk, please wear safety glasses, don't drink before swimming, keep 'yer stick on the ice, etc, etc.
