The file 'AA Battery Holder (lockable) For Rechargeables 3D Printer Model' is (stl) file type, size is 10.2MB.
For the rechargeable batteries I designed a holder. By rotating the top part, one battery can be removed at the time. If all batteries are loaded or empty, the top part can be put into an intermediate position and it will lock all the batteries inside. No risk for loosing uncontrolled battery/ies. Like this they can be stored.
You need 1 screw of M3 size
Design is inspired by the fact, that my son has a little RC car which is truly energy-hungry and I need to hold one set of spare batteries always in place. A missing battery would result in "serious" issues :-)
