Adjustable extending chair slide

Print yourself a new chair slide when the old one breaks. This one is designed for a nominal 10mm ball head. It will require some force to get the ball end into the socket; I used a vice, but gentle use of a hammer should work as well.The commercial product is made from nylon, but this model is PLA, which has worked fine so far. This was a pretty simple first model for me so don't waste a boost on this one, but Thank You anyhow :)
