Customizable elbow for joining PVC pipe

This is a general-purpose elbow for creating frames or covers with PVC pipe or conduit. I was working with "15-mm" pipe that had an outside diameter of 21.5-mm (~27/32 of an inch) but you can easily change pipe_ext_diameter variable/parameter for different pipe dimensions. You can also specif how many arms/way the elbow join needs by changing the pipe_arms variable. It works to make elbows to join 1 (why would ya?!?) to 5 pipes but I have only test printed 3-way and 4-way.

The internal diameter tapers very slightly so the pipe will stay in there without glue.

Let me know if you need changes made.
