Hello again you all, Ive been working on my first saber and Im just waiting on my PRIZM to ship but I have all the other parts of my saber built and was able to test all the LEDS by connecting them directly to the battery (resisted, of course), but Im noticing my 18650 Panasonic battery does not fit as snugly in the Acrylic Chassis Disc for PC 2.0 and 18500/18650 pack - S2 as I feel it should. Should the battery fit super snug on its own, or do people typically use some additional measures like tape or some kind of fastener to keep the battery in place?

Any advice is greatly appreciated.
