Adapter to allow attaching Canon EF lenses to a P8079HP image intensifier.
Added compartment to allow inserting 18650 battery holder and switch holder.
Ability to insert nuts and bolts to tighten the night vision tube.
Uses code from:
- http://www.thingiverse.com/thing:1029872/#files - for the EF mount. I adapted this to add locking tabs.
