AA to C Battery Adapter

Use AA batteries in place of C sized batteries.
I created this as a light weight (Cura says 1.56 g) stylish alternative to existing designs.
I printed mine with 0.4mm walls using Cura and an Ultimaker out of PLA.
If dropped with a battery in place, these can crack. But, it only uses 18cm of 3mm filiment.
I hope you find this useful and interesting.
