This is a collet to lock a telescopic rod made of two tubes (e.g. aluminium or PVC) of such diameters that one fits snugly in the other.
This is a redesign of my other model, easier to print, easier to customize in the code, easier to fit the tubes, easier to fix if damaged, and cheap to reconfigure when your needs (i.e. used tube diameters) change.
If you're using the attached models, you're expected to put your own holes through the compression crown and reduction sleeve (e.g. add negative volume in Prusa Slicer). The OpenSCAD code can, of course, generate them ready with holes.
Some uses of a telescopic rod in a workshop:
- fixing rod for a bike maintenance stand, to keep the handlebar and front wheel from moving during work
- pinch rods for woodworking, to check squareness of a box or drawer glue-up (diagonals are the same length) or to measure inner dimensions of places awkward to reach with a tape measure
