Adjustable 3/4" PVC Angle Connectors

Obviously, this isn't for PVC you are using to pump liquids -- it's for building structures. If you want to join 3/4" PVC pipes at an arbitrary angle, try these. One set (a pair of double and single "spines") works well for angles up just beyond 45 degrees. That set is the stronger set. By moving the hole out a little, the second set provides a wider range of angles at slight cost in strength. I used 2mm walls and 25% infill with PLA+ and they are plenty strong enough for the indoor awning we used them on.

Mine fit nice and tight, so I didn't need to use the screw holes in the cylinder parts to attach them to the PVC, but the holes are there just in case you need them. All holes are sized for #8 bolts.
