im 3d printing light caps.
Streamlight uses 4 major bezel dimensions, the pistol light TLR (have that measurement), the ProTac HL-X which has a bigger head (got that measurement) and from what I see the regular ProTac from the OG product and the ProTac 2.0 which appears to have a different light head and bezel.
Im looking for a millimeter measurement on a pair of calipers for the ProTac and ProTac 2.0 light head bezels.
If you could contribute this information id be more than happy to provide you with a mock up of what im working on for your help.
