Friction Welding Rod

Just some 30mm x 3mm friction-welding rods, in case you don't have 3mm filament or are bothered by its tendency to bend and snap from the chuck/collet at high speeds. Print with "concentric" infill at 100% density, no support needed. OpenSCAD file included if you want to tweak the length, radius or tip angle. I print them in batches to reduce the dwell-time since these are so small.
