4 AA Battery Holder Pack V3

Improved battery holder, holds 4 AA batteries. Uses snap lock lid and spring contacts.

I'll add build details in post processing once version 2 of this finishes printing - if you need details sooner check out my Gutter Downspout 180 Joint project on how to use filament joints.

BOM:

• QTY 8 Battery spring contacts (https://www.aliexpress.com/item/32884289489.html)

Optional nut and screw if you need a more secure lid but after testing I found built in latch to be sufficient

• QTY 1 M3 X 10 Button Head Machine Screw (https://www.aliexpress.com/item/32798146322.html)
• QTY 1 M3 X 6 X 5.3 Embedded Nut (old link no longer works - possible substitution M3 X D5 X L6) https://www.aliexpress.com/item/4000232858343.html

Files updated 9/4/2020, tweaked some of the fit issues and added a snap on type connection to the bottom, I'd still glue together the bottom and the case but this might hold without glue

Updated 9/5/2020, improved fit issues with the bottom, added (+) / (-) indicators and clarified wiring routes

Updated 9/9/2020, minor tweaks to bottom and top

Updated 9/10/2020, caps were too small for larger diameter wire and post were too flimsy to hold cap in place, revised caps to be larger and use glue on installation
