Pex 1/2" Elbow Joint

cults3d

I"m running my garage door openers wiring inside some 1/2" Pex tubing to clean up the ceiling and rid it of the random wire chaos that i inherited with my house. I decided to make my own adapters/fittings to do this. This is an elbow, The outer diameter is 19mm. Each end has 15mm of a 16mm diameter (1/2" pex is 15.8mm so there is .2mm space). The pex tubing fits snug in this end without needing glue etc. Other pex parts: Inline Coupler - https://www.thingiverse.com/thing:5388158
