Nerf Hyperfire Battery Cover - w/ Volmeter Port or Simple

thingiverse

Pretty straightforward - needed a replacement battery cover for my Nerf Hailfire blaster. Printed the one already published on this site, but it didn't fit right. Decided to add a voltmeter (13mm x 22.6mm) to the printed design and also included an extra flat cover for those who prefer simplicity. Doubt the voltmeter will work with D-size batteries, but should fit fine with LiPo or other replacement batteries. To make it work, you need to print both the cover and the clips that connect into the blaster - easier to print them separately and makes modifications a breeze without re-printing the whole battery cover. The clips and voltmeter are a tight press-fit (may require a dab of glue on the screw plate clips). Had to file a bevel at the start of the voltmeter hole to get it in smoothly and don't need any extra glue - just avoid inserting it upside down, or you'll struggle to remove it. May want to ensure your corners are flat instead of curved since that's where it rubs.
