This extra large battery dispenser is designed to hold both AA and AAA batteries, 20 AA and 23 AAA. I have also added a version that holds up to 16 AA and 18 AAA batteries. If you're looking for a smaller model that holds up to 12 AA and 13 AAA batteries, have a look here.
There is a Voronoi pattern on the sides of the magazine to make it easy to see how many batteries are left. The drawback of this design is that batteries can fall between the rails when inserted. The back follows the curvature of the magazine, reducing the risk of batteries falling out during loading. However, you still need to be careful when loading.
The battery dispenser is screwed to the wall. This ensures that the mounting is strong and secure. To assemble the battery dispenser, place the right and left wings together and overlap them, then insert the screws through the screw holes and screw into the wall. Use a flat head screw that fits countersunk holes with a diameter of 3-3.5 mm and a length of 16-20 mm, but this may vary depending on the type of wall you have.
The battery holder is long and the smallest possible print bed is 220x220mm and each side of the battery holder will have to be printed separately to fit the print bed. For the best results, print the battery dispenser lying flat on the side. In the model files, the parts are orientated in the direction best suited for printing. Use e.g. PLA for printing with a layer height of 0.2mm and a nozzle width of 0.4mm or less. A wall thickness of at least 3 lines and an infill of 25%. A support structure is recommended for the screw holes.
Feedback is always good. To encourage me or other designers to make more models, please hit like and/or post your makes. If something doesn't work or is missing and can be improved, please leave a comment.
The author remixed this model.
May contain more batteries.
