Spool Holder for Plano 1612 "Deep Water" Dry Box

thingiverse

I take no credit for designing the dry box itself or the concept of a dry box. However, I created the spool holder myself to be used in conjunction with a Plano box. I was drawn to using an ammo can to contain filament because it's sealable, pre-made, and easy to use. The problem is finding an ammo can large enough for an 8 inch spool. Plano makes one such box for ~$20, the "1612 Deep Water Resistant Field Box." I bought mine on Amazon, but Walmart supposedly sells them as well. The file I have uploaded is a simple holder for a closet rod or pipe of 22.6mm in diameter or smaller. The holders have a curve on the bottom to sit in the groove along the inside wall of the box, and I held mine in place with tape for convenience. Print two holders and cut your rod at 6.75 inches long. It will span the width of the box and sit on the holder, allowing you to put your spool on the rod and simply drop it in. Most standard 8" spools have just a couple millimeters clearance from the bottom, which is all they need to spin freely. At least one 1kg spool fits inside, and a second spool at .5kg should also fit. My Carbon fiber spool (which I designed this for) is thin enough to fit alongside, but I have yet to test two spools in action at the same time. I used pneumatic connectors and a bowden tube to run the filament out of the box, but that's entirely up to you.
