If you are like me you have a lot of tools and a lot of batteries to go with them. I like to pack my batteries securely when I take them places. This 'Battery Packer' will allow you to pack 2 - 18 Volt Ryobi One+ Batteries at a time in the minimum amount of space and no flopping around. The batteries lock in and cannot be inserted backwards.

Takes about 8 hours to print on my Ender 3 using my Cura settings, all planned for speed. I have included the fusion file (.f3d) , the .stl and the .gcode.

If anyone can figure out how to add the Ryobi logo to the sides that would be great but I couldn't figure it out.
