F450 drone frame battery holder

thingiverse

Simple holders for keeping a battery in a "F450" drone frame from sliding out. The distance between the two (3 mm diameter) holes is 34 mm. There's a 14 mm wide notch on the top and bottom parts to hold the fastener in the middle of the slot. There are three different types of *lower/bottom* parts, all of them have recesses for two M3 nuts. The wider ones are designed to be feet for the center part of the drone (if you want to place it on a smaller surface). If you have a landing gear or longer feet mounted, you don't need/want them. These bottom parts are *optional*, you may also just use some matching washers and M3 screws/nuts on the bottom side. (The wider parts in the pictures are a little bit older, but the basic size is the same, I only added some more material and rounded the edges.)
