Summary

I Remixed this to hold 5 21700 cells for a powerbank that Im doing. I am doing GreatScott's (Youtube) powerbank and decided to use 5x 21700 cells instead of 6 18650s. The shortened version I found fits better in the case he created and the weight distribution seems feels nicer (not to mention less chance of the batter pack coming unstuck and moving around). Fits fine at 100% scale if your printer is dialed in, I printed it at 102% scale and that worked best for me.
