Foam Proton Pack

I needed a lightweight pack built quickly. My solution was insulation foam. It's easy to cut and sand.

I did one foam pack at 50% scale for my son, and a true scale pack for my wife.

I cut the foam primarily using a table saw. I sacrificed a few details due to time.

I glued the pieces together using spray adhesive, I'm hoping it holds up (which it did!). I coated the foam with a styrofoam coating that preps for paint- MagiKote. The foam pieces were glued to a 1/8" hardboard motherboard.

The mini pack motherboard is epoxied to a 3/4" pvc frame. I printed lables from Hprops at 50% scale. They were attached using spray adhesive.

I cut backpack straps and zip tied those to the pvc frame. Vacuum hose from a GM vehicle was re purposed for the pack hoses. The split loom is 3/8". A 3/8" dowel was epoxied onto the wand and the motherboard of the pack. Then the split loom was epoxied to the dowel.
