Created a 20 slot battery holder for BT2.0 1S batteries made by BetaFPV. There is some wiggle room built in for if/when the batteries expand a bit from use or heat. The slots are 8mm wide x 16.5mm length x 30mm deep. This was designed this way so that people can read the writing mAh rating a little easier. The taller 550mAh batteries will stand out in height if that matters to people (making it universal for depth seemed like the right thing to do). Feel free to scale the file in a slicer if you want to cover more of the battery height. This will fit 450mAh and 550mAh batteries for BetaFPV drones and maybe other braand 1S batteries? Check your own dimensions if you want to use them for other brands.
I've included a .obj file if anyone likes using those when slicing.
