Another flashlight diffuser.  In a typical diffuser you'll notice a hotspot at the top of the diffuser.  This design attempts to distribute the light to the sides.  Depending on material and your printer, you may need to slightly scale larger if it's too tight of a fit.

Have validated the following:

The 24 mm version fits the Convoy S2+, S7, Sofirn SC31 Pro, Wurkkos FC11/11C

The 28 mm version fits the Sofirn SP35

The 32 mm version fits the Sofirn SC33

The 35 mm version fits the Convoy M21B

If there are others, I have provided the fusion file or let me know the flashlight head dimensions, and I'll upload additional profiles.
