This is a very compact modular battery pack which fits into a 32mm plastic (electro installation) pipe. It is devided into segments which can be added to a pack of 4, 6, 8... or even more AA-batteries. It is great for building lightweight, compact and tough battery packs. With watertight pipe plugs it can be used for outdoor and underwater equipment.
The single segments will be fixed on a M3 threaded rod which makes the construction simple but strong.
The pack was originally designed for a DIY metal detector https://www.thingiverse.com/thing:2478864, avoiding an additional housing for the battery.
The inside diameter of the pipe must be somewhat 29 mm.
You will need:
- printed parts
- battery connectors (common type, can be found in several electronic shops)
- M3 threaded rod, about 1,5cm longer than your plastic parts
- 4x M3 nuts
- packing cord or a cable tie which will act as removal sling
