SUNLU Official Filament Dryer S1 Plus, Built-in Circulation Fan, Filament Dryer Box Storage Box for 3D Printer Filament 1.75 2.85 3.00, S1 Plus White

I don't understand why you think you can't print or have a printer in a high humidity environment? You think the whole state of Florida and the south as a whole don't use or can't use 3D printers? People print and live where the humidity is literally 100% on the daily. Keep your filament stored in sealed bags with desiccant packs and dry your filament before use. You can get a Sunlu dryer for like $40 and almost all have options for PTFE tubes so you can run the filament from the dryer to your printer. I have a ComGrow dual dryer that works great and was only $45 on Amazon. https://a.co/d/0flXR9mv https://a.co/d/0ge9Wqt2

Easy. Good filament storage options are always a useful thing to consider. Improper filament storage can most often create subpar results and massive frustration. An inexpensive gift would be gallon sized freezer bags and a bunch of desiccant packets. Toss in a couple of packets and press out as much air as you can before sealing it, keeps the filament from absorbing moisture that can create printing issues. Both items together is around $25. Something a little more expensive would be a filament dryer. I have a Sunlu dryer, use it religiously with my more expensive filaments before they go into the freezer bags. Also helps keep filament dry during a lengthy print, especially if you cannot escape a humid environment. A final addition to this particular list would be a vacuum sealer (example, my sealer is no longer being made), this is the most effective way to keep occasionally used filament spools fresh so they print well. The bags are thicker than the freezer bags and, IMHO, keeps my expensive filaments (carbon fiber, wood filled, nylon, PETG) in excellent condition. I have a roll of wood PLA from 2019 that goes alternately between a freezer bag and then the dryer anytime I need to reprint a particular file, still prints like it did on day one. The bags become a little expensive but can be reused if you trim them carefully. I used the desiccant packets with the vacuum sealed bags as well.
