Modular 18650 Battery holders

This is a modular battery holder. Print the holders individually, as many as you want without knowing if the next project will need 1, 2 ,4 20, or 100 batteries. Just print a larger tray and slide the pack onto it. Print the battery holder itself in PETG so it can have some flex, the tray can be PLA. Additionally, design your builds without worrying how the orientation will affect your battery tray. Just grab the simple tray and remix it to your own projects, then later slide the 18650 onto it. Build your own battery packs, you can wrap the nickel around the backside and make the tray and the battery slide terminals. Just add a little heat and let the nickel strap melt into the tray or holder, or both. The tamper, which is used in PJ's design allows you to shape the nickel straps
