12-spline cassette lockring tool / fork air spring topcap tool — 3/8 in drive

I needed this tool to remove the air spring topcap from my Fox 32mm TC (taper cast) fork and install more volume tokens. It should also be compatible with other forks using the 12-spline cassette tool standard as the original creator mentioned. Can be used on cassettes as well of course. The only difference from the original model is the shrinking of the socket size to 3/8 inch.

I printed this in PETG with 20mm layer height, 100% infill, and 6 walls. Perhaps not optimal but it worked. It was able to remove my topcap and re-tighten to 220 in-lb (24.8 Nm) with only some minor rounding out of the socket walls. 

Changed the socket size to 3/8 inch.
