PVC Spool Holder Foot

This is a basic foot for 1/2" PVC pipe, to turn it into a cheap, easy to make spool holder.

What's awesome about this spool holder is that the length of the upper pipe can be cut to any length, so that you can hold as many spools as your heart desires!

The feet have a diameter of about 147 mm, so it can be printed on a Printrbot with no brim/raft or large prep circles. The design leaves a little bit of wiggle room for the PVC, but the PVC will stand straight nonetheless.
I have about 6 spools on my holder, totaling out to about 4.2 kg (9.25 lbs)

This flange-shaped foot doesn't necessarily need to be used for a spool holder... It could be used universally to attach PVC to walls/tables/etc.
Feel free to modify the design files however you like!
