Solid storage for 12 AA battery cells.

I had seen another project using dans98 thread profiles for Fusion 360 and the battery storage contest seemed like a perfect opportunity to set them up and try them out myself.

The threads came out perfectly, first time, with 0.2mm clearance. They have a smooth positive engagement. 

I printed in Polymaker PolyTerra PLA

4 perimeters, 12% infill, 0.2mm layer height

Also added a smaller AAA Version
