12 Gauge Desiccant Hull for Long Term Storage

Here's a desiccant holder that fits in any 12ga with 2.75 chamber. Good for long term storage. My friend thought of the idea and here is the end result! 

Don't put a bottom or top layer and the case head end and the opposing end of hull will have just the infill design. My friend also told me about that technique. Thank you sir! Infill is about right at 40-60%  so it holds the desiccant. Thread ends go up on plate.
