Thanks for trying i had also thought that could be a possibility.
I tried with a plier on the brass part, but no luck so far.
I got my Jexree mini today, it is a very nice aaa & 10440 capable light for 5$, slightly worse reflector than the hugsby but much shorter and very nice anodizing.
And it is completely modable it looks like the best 10440 host i have found yet.
Every part is easily accessible, lens,led star,driver,even the bottom spring. Driver compartment is 6,6mm deep, driver is 12,6 wide, led star sits on a shelf thats is 13,8mm wide. EDIT i made an error when i measuring this initially, the shelf that the star sits on is 12,4mm wide.
First i am going to put an XP-L V6 3D on copper in there, then i will try to find a small fet dd driver that will fit.
