Ultimate Spool Holder Dry Box - hex head bolt version

This is a remix of [The Ultimate Spool Holder Dry Box](https://www.thingiverse.com/thing:2929701) using 6" long 5/16" hex head bolts instead of the steel rods, because that's what I could easily get from the local hardware store. The assembly is more finicky because it's not one long rod on each side, but I do get to use nuts to keep the 608 bearing holders from sliding around. I also made little standoffs to prop up the bolts.

It's not perfect, but works for now - I might even stop tweaking this setup for long enough to use the printer for something other than to tweak this setup... Uhmmm, I just need to get the bowden taps in place and then it'll be "good enough". Oh, and then maybe make something to keep PTFE tubes neatly laid out. The silica packets are kinda just sitting there, maybe make a basket for those? And the humidity monitor is too large and needs to be off the floor of the bin... Sigh.

**BOM:**
4 x 6" long 5/16" bolts with 13mm hex head, 2 on each side
2 x Rod hol
