Yet another bottom bracket tool. This one is designed to fit VP-components BC73 (68) fitting. It has 20 splines rather like the Parktool BBT-22/32 (and many others too). The BIG benefit of the VP-components fitting is that there are also four larger flats, each bridging two splines. The benefit is that this tool can be printed strong enough to be used to fit the bottom bracket. I suggest using a fine setting and 100% infill. I have made the tolerances tight to maximize tool strength. I have also included the solvespace file should you want to modify the desgin.
