Remix of Original File by Tmarentette. None of the other models available fit my setup the way I wanted, so I remixed my own (with some emphasis on retaining STL quality).

V2 (best)
Slightly looser fit then V1 but allows for 1 handed removal and carts/batteries fit in any hole now.

Changes from V1:

• All holes now slightly larger then original and V1
• All holes now the same size (11.6 mm)

V1 (snug fit)
Battery needs 2 hands to remove and you can only fit carts in outside holes (both issues addressed in V2).

Changes from original:

• Center hole size increased to accommodate 11.2 mm battery
• 2 outside holes increased by .1 mm
• Lengthened USB charger holder area
