A great way to make props collapsible is to split the PVC pipe and install a joint, but commercial joints tend to be either difficult to find or bulky, as they fit to the outside of the tube. 

PVC pipe, as you may have noticed, also comes in different sizes. It's measured by inner diameter, but that varies slightly depending on whether the pipe is schedule 40 or schedule 80. Annoying, right?! It can make it really hard to find something that slots into each end snugly without being too loose or too tight.

These twist locks add an extra bit of security for separation. These printable tubes and sheaths slot into each end of the PVC pipe, so you can glue it in one side and then slot that into the other part to take it apart or put it together. Part A has a nub that slots into part B and then rotates 3/4 of the way around so it cannot slide back out until you rotate it back.

You can figure out which size you need to print by looking at your PVC pipe; it should be printed right on it whether it's schedule 40 or 80.

To install, the sheath should be flush with the edge of the pipe, and the connecting tube should sink in until the split between the thicker part and thinner part.

We've since updated this kit to include a channel inside for a support beam we'll include with the kit. This adds a ton of extra strength to the connectors. See the video for details on how to install. You may need to give the beam a light tap or two with a hammer to secure it.
