This prints in 35 minutes and uses 1.1mm filament on my printer. Printed with 90% infill (gyroid if you have it).
Please give me a like and post your print. I spend a lot of time making minimalist items so everyone can save time and money and have less impact on the environment.
This works for both rechargeable and disposable batteries. Rechargeable batteries are ever so slightly wider and fit nice and tight.
