Traxxas 5347 tool for Delta printers

This is an easy to print, easy to use tool to help with assembling Traxxas 5347 ball joints, used in many Delta printers.

The pictures show how to use it.

The steel ball piece is guided by a 30 mm M3 screw and should snap in place with a firm press of the conical pusher.

OpenSCAD source is included so the thing can be remixed if needed.
