I saw a universal joint recently and thought with a bit of pressure you can lock the joint in whatever position you need. I created two connecting pieces, one to use with washers and the other without.
Parts
Optional Parts
1/2 inch rubber washer of some kind kinda helps with a grip with tightening. You can use the connector that does not need a washer but you may want to use a metal washer on the outside to even out the pressure.
Here's the washers I have on the photos.
