What kind of glue are you using the hold the EVA foam together? I need to look into building a few packs for my kids. This looks very promising and makes it much lighter for them to tote around.
I built this one for my son about 3 years ago. Most of it is foamboard, the rest is junk parts I had lying around. None of it is screen accurate...I was just going for generic look.
Can't wait to see progress on this build!
