3S LiPo Battery Spacer Kit for Traxxas Rustler 2WD Trucks

This is another wedge and strap designed specifically for longer 3S LiPo batteries, like this one here: https://www.thingiverse.com/thing:3657141. I created it to accommodate batteries that are too long for the standard tray, not too thick like my previous design. Initially, I thought I had all the dimensions correct, but the length didn't account for the wires protruding from the pack's end, and I didn't want to bend them excessively, so I designed another wedge and strap to secure my 3S batteries in place. The specific battery I have is the GENS Ace B-45C-3300-3S1P (https://smile.amazon.com/gp/product/B07C3MKZTS/). I improved upon my previous design by making it reversible, allowing you to use it for batteries that fit the tray properly without having to carry around a flat strap. Simply align the pin holes in the hex posts with the slot, and you're good to go. For easier removal, I recommend threading a string or similar object through the pin loop. I print these wedges at 100% infill to ensure they can withstand the occasional collision between my truck and a curb that happens in my cul-de-sac from time to time.
