Splined Bottom Bracket Bike Tool

This is a splined bottom bracket tool for installing/removing BBT-32 style bottom bracket cartridges. The OpenSCAD source is parameterized so it can be easily modified to accomodate other splined bottom bracket sizes. I have printed this in PLA and used it, it does work, However, because of the forces applied when using this tool, 100%, or near 100%, infill is highly advised.
