Revolver themed AAA battery storage container (parametric)

thingiverse

This is a container designed to hold six cylindrical batteries with an AAA size setting that can be adjusted. It remains untested for now. The update log shows that on February 2, 2017, clearance was added to the holes allowing easy insertion and removal of the batteries. A ratcheting mechanism adjustment is needed to accommodate a larger, stronger spring. Assembly involves printing the body and cap pieces first. Next, an M3 nylock nut is inserted into the nut trap at the bottom of the body piece and pushed all the way in. An M3 cap screw is then threaded through the cap piece. Springs with a 2mm outer diameter are inserted into three holes at the top of the cap piece, followed by the installation of ball bearings on top of each spring with a 4mm outer diameter. The cap piece is then secured to the body using the cap screw. When done correctly, this should allow for the cap piece to be turned relative to the body, locking into 12 stable positions. Six of these positions correspond to battery holes and the remaining six are in between them, keeping all six batteries secure within the container.
