I made a couple of dry boxes myself. I use the rubbermaid 22 cup storage containers as I’m printing in an enclosure with limited space.I ended up making a dry box that will hold 4 spools. You can also feed directly from the box without removing the spools so they always stay in the controlled environment. Here is a link to the one I made.
The Ultimate Spool Holder Dry Box by ritchrock
I've been using TUSH (The Ultimate Spool Holder) with great success and wanted to make a dry box around that concept. I also wanted to minimize the number of holes put into the sealed container. I found the "Hefty 20qt Filament Box" project and decided to remix it for the Sterlite Gasket Box...www.thingiverse.com
Do you know which hot end you're thinking of upgrading to? I went with a Dragon hotend and it's been great for everything I've done. If I had to get another and was willing to spend the money I'd probably get a mosquito.
I will be upgrading to the Micro Swiss, with exoslides and a silicone bed heater from Gulfcoast Robotics.
