For those without access to a lathe. I draw a circle with a fine felt tip pen and a drawing template. Remove the material outside the circle with a bench grinder (big wheel, fine grain). Put a light on the brim of your baseball cap for better vision. Firm grip but low pressure does the trick with plastics.
Or you can do it the way I’d do it:
Sit down at your desk with a handfile and some music and start grinding. Shouldn’t take more than an hour to grind the star and optic to a suitable size.
It’s not very efficient or fast, but it is cheap and easy. I’ve ground down many stars over the years by hand this way and never had any trouble keeping them centered.
https://www.ebay.com/itm/Dalex-2-Way-Mount-Adjustable-Size-4-25-4-75-Wide-Folding-Knife-Sheath-Pouch-/323241571760. Vertical or HORIZONTAL nylon belt pouch. This should be a perfect size for this light. It looks like the label is simply sewed on and should come off easily. Not many left. Raine Inc makes a “deluxe knife sheath” in a few different sizes and one of them might work also but there are not many other choices for horizontal carry. Light and pouch enroute.
Can you please link that thread? Thanks.
Found it.
You know what you have to do now, right?
…
Get her a matching diffuser cap, put the light in candle mode, and prepare her a nice hot bath. :innocent:
I still can’t find it. :person_facepalming: . Link please… 
Hope it works
/\ Thanks for the link gentlemen…. 
FW3A Quad in a word…Yuck!
. 
Why yuck?
I received my FW3A shipment and stuck 219Bs in one of them right away. Next up is sliced dog farts (5000K LH351D). The stock XP-L HI 3D is pretty ugly (Duv 0.0035 or worse on practical levels), but it’s much nicer with sw45k

Alot is cut off/out at the bezel, the beam is kinda Funky, outside on Turbo not too bad for the few seconds you can use it…. and I mean seconds…. I prefer the triple….
Fair enough. Still impressive skills though.
Thanks!
. Here is the Funky Square-ish Beam it produces… 
Yeah. Are you going to change it back, or try other emitters?
Oh my gosh !
CRI70, not a good Duv, desaturates most colors (over-saturates green-yellowish), lot of hue shifts and colors fidelity sucks.
I only ordered a Convoy desert S2+ with XP-L HI 3A and was done with XP-L HI. How could people always asking for this expensive and ugly thing for the sake of a tint and a bit longer but ephemeral turbo ?
Quick and nice work still KB! Which 106xx optic did you use?
