Battery stand for keeping track of rechargeable batteries. I keep the battery stand on my desk as my headphones uses AAA batteries and needs regular changing.
Since I don't have (don't want) a charger on my desk the uncharged batteries got mixed up with the charged ones so I made this thing to keep track of them.
Also, as long as there's some charged batteries left, you don't have to get up and put the uncharged ones in the charger.
I've smoothed the surface a bit using sand paper and metal polish on the battery stand in the pictures.

Clas Ohlson PLA
It should be fine printing with a less infill, even 5-10% should be fine for durability, but if you'd like a bit more weight to it you should go a bit higher.
I printed mine with 30% which is ok, but I'd like it to have a bit more weight so if printing it again I would go with 60-80% infill.
Also, don't recommend the Filament brand, it's just what I used, Prusament PLA have been working really well for me lately.
