This is a set of Multiboard compatible Battery Holders for a variety of size batteries. Rather then focus on holding as many batteries as possible, these holders are designed to hold a reasonable amount of batteries in a modular fashion so that you can mix and match. You can add or remove holders as your needs change.
Currently it contains holders for AA, AAA, C, D, CR123/A, 9 Volt and 18650 batteries.
The holders are 50mm x 100mm and can be organized modularly and printed so that you only have holders for the batteries you need and use.
The holders have the same depth, except for the D or 18650 holders which need to be a little deeper to hold the batteries in securely.
These holders are designed to be able to mounted in Portrait or Landscape orientations. The holes are angled in such a way that if oriented with a small arrow facing up, the battery will be angled upwards to help prevent it from falling out.
This version is designed to use M3 button head screw bolts and attach to either the Heat Set Insert Snap, the Heat Set Insert - Push-Fit, or one for the Drop in Nut Snaps
