battery spacer

Hey, i was looking for, and trying different things to act as battery spacers for my mag lite builds . ( i am currently using an SBX driver with 26650 battery for 3.5 watt diode.) Then it dawned on me , why not use a 50 amp fuse. Sure they are more the size of 18660 cells , but with the right size pvc pipe liner- perfect! Cheap too (3.89 for 2 at Menards "http://www.menards.com/main/electrical/rough-electrical/fuses/50-amp-cartridge-fuse-2-card/p-1449425.htm?cm_vc=PDPZ1"

Trust me, it is much better then springs or chicago screws .
