Hurst E3 Battery Mount

This is for the Hurst E3 Edraulic extrication tools. No one makes a battery mount, so you're forced to let them live loose in a cabinet or spent $500-650 per charger to mount them securely. This is a cheap option, and it works great. This is a modified version of the file on Printables. We have had 3 of them mounted for over a year, and because the batteries were loose, when we hit a rough section of road the batteries would jump up in the mount, causing them to fall out of the mount a time or 2, but more importantly noticed with ABS, printed vertically, in sub zero temperatures, that heavy battery coming back down cracked the holder pretty good. This happened once, we thought it was a fluke, happened twice, I switched to PETG-HF, and then as the other 2 ABS mounts broke I printed the rest in PETG-HF. PETG-HF with the same settings hasn't failed me yet. The only thing is, they still bounce around, and several parts of the battery contact the holder. I was looking to improve the design
