AAA TO AA - ADAPTOR - with 2 M4 Nuts

thingiverse

I have 4 rechargeable AA batteries but most of times i find myself im running out of them while i have to charge them, and i also have a bunch of AAA batteries rechargeable so i made an adaptor to be able to use the AAA as AA for my wireless mouse when i recharge the AA batteries. **the hexagonal hole is for m4 bolts but is a bit bigger. if you print with 0.3 should fit almost snug unless the interior walls warp and then the hole becomes smaller** i print it at 0.28 the hole is a tad bit bigger but then i melted the bolts inside using a lighter and the cleaning tool for the bed. Hope it helps someone. You can do whatever you want with it i don't care. If you have problems with the first layers not sticking u can add some brim or slow the first layers down a bit. im running it pretty fast. The end assembly should look something like in the photo AAA snaps inside the support, pushed max to bottom has the same length as a AA battery and thickness. You can take the AAA battery out by holding the support and grabbing the exposed battery outwards. It's a tight fit, some batteries have paper wrapper that is thicker and might get a little bit scratch at the base since that's where the support is most rigid and doesn't move.
