18250 battery?

Hi,

If you look at Old-Lumens thread here:

the 1st post has some pics of the “pill”.

On the emitter end, that pill has a ridge, and the emitter board sits on top of that ridge.

From my pics above, the 3up board has 3 small holes, intended for screws, to attach it to the pill. I want to try using screws, but am wondering if I can just drill 3 holes in the ridge, and use some self-tapping screws to secure the 3up board to the pill? I’ve eyeballed the pill sitting in the light, and it seems like it’d be ok (i.e., I can see the ridge through the holes), but was wondering if anyone knows where I can get a small quantity of such small self-tapping screws?

Thanks,
Jim
