1.25" (31.8mm) Tube Clamp / Bicycle Seatpost cutter fixture

I needed to cut a seatpost for my son's new (used) bicycle since it needed to go shorter. At first I tried to clamp it to the workbench without any fixture and C-clamps. It was very difficult. So I whipped up a quick tubing clamp for the 1.25" diameter seatpost. It had enough bend to work on the first try. Has a 0.75" circle centering indentation so the 3" C-clamp won't slide off.

If you need a different size, just scale the STP / STL file accordingly (or you can ask me to do it for you)
