I designed these holders as I was getting tired of having to unclip the batteries from them when I need to use them. I find these much easier, have not fallen out of my ute while testing/driving around.
These simply slide in from the top and slide up when needed, no more having to wiggle the lock tabs loose especially if they're up high or near a roof like in a canopy for a ute/truck.
Due to tolerances being snug for my prints, please ensure filaments are dried and tuned including pressure advance which will enclose corner tolerances :)
I have printed these in PETG to withstand the heat inside trucks/canopies but I imagine they will fair very well in PLA for garages or cooler areas.
0.20 layer height, 5 walls all round, top and bottom, 15% gyroid infill but play around with these to what you feel is best.
Happy printing! :)
