I made this battery holder for organization of AA, AAA and 9V batteries, because I couldn't find a battery holder, that I liked, and was able to hold AA, AAA and 9V batteries.
I hope that you guys like it, because I spent a lot of time making it, as my first 3D design ever made.
Feel free to tip me, if you want... :D I'm saving up for my own 3D printer, because I always use my school's 3D printer.
I printed this with 0.2 in layer height, and it turned out very well. It took about 5 hours to print, but it was worth it, because I now have a useful battery holder for all my batteries.
Overview and Background
The 3D model is about 148mm long, 100mm wide and 20mm high. The holes for the AA, AAA and 9V batteries are universal, and fits nearly every AA, AAA or 9V battery.
