Flashlight diffuser for Emisar D4S E07 39mm bezel torch

EDIT: 2/26/19 - Uploaded MK.2 diffuser. Reduced size slightly and optimized a little more for flood than throw.

EDIT: 6/14/19 - Split the D4 diffuser off into its own project, see https://www.thingiverse.com/thing:3691725 for ongoing development of the D4/Medium universal diffuser.

EDIT: 6/22/19 - Removed Mk.3 diffuser as it shows some strange aberrations in the output pattern. The Mk.2 is still the top performer at this time. Also added step-up ring to use with Fireflies E07. This ring might be tricky to print as it is fairly thin.

EDIT: 7/10/19 - Added Mk. 2.5 diffuser, minor updates mostly behind the scenes, changed mount type. Updated E07 adapter to be one layer thicker, may require light sanding now.

A large lantern/diffuser made for the Emisar D4S high-power flashlight. Should fit any light with a 39mm round bezel. If you own this light you know it can get really hot, I wouldn't recommend using this diffuser for long-term turbo use. Print open side up, no support needed, with or without gap fill, 5-10% infill recommended. GITD translucent material recommended.
