Filament Spool SyStem V2.0

cults3d

The goal of this project is to keep the filament dry and dust-free for many months after it has been removed from its shipping bag. To achieve this, I've accumulated some filament colors and types that I rarely use, keeping them in perfect condition. 3-6-2019 UPDATE: For over a year now, I've been using packaged drying agents with impressive results. You can find the brand I recommend on Amazon at https://www.amazon.com/gp/product/B01BEEVDVK/ref=oh_aui_search_asin_title?ie=UTF8&psc=1. This brand's bags are incredibly durable - they seem to contain some cotton fibers in their paper. To recondition these bags, simply place them in the microwave for 30 minutes on the defrost setting; avoid using regular heat. You'll notice the bags swell up as water vapor is released during this process. I then store the reconditioned bags in a ziplock bag. On the other hand, color indicator desiccant packets that come in plastic bags do not work well for me. When you warm these bags, the plastic becomes brittle and you end up with loose desiccant scattered everywhere. 3-4-2019 UPDATE: The 21-cup cereal containers I use can be found on Amazon here: https://www.amazon.com/Rubbermaid-LEPUSEMTE469-711717429496-Container-Everyday/dp/B00XJRMW5M/ref=sr_1_fkmr1_1? and also here: https://www.amazon.com/Rubbermaid-Modular-Storage-Canister-1840750/dp/B00BEUDWIC/ref=sr_1_fkmr1_1? 6-11-2018 UPDATE: I've noticed that eSun spools vary in width. They use the same bolted-together plastic and tight bolts, but there's still a variation. Because of this, I advise against using the eSun cross bar STL files, which have detents intended to provide correct spacing for side roller pieces. If you're using eSun filament, I recommend using standard cross bars but gluing only on one side - leave the other side free to move in and out. The Filament SyStem is now at version 2. The main change is that I've made the desiccant holder a bit smaller to accommodate a less expensive Rubbermaid 21 cup dry storage container, called the Zylar Container. However, you can use any plastic dry storage container - any size and any brand. Since I only use eSun and 3D Mars printing filaments, I don't know the sizes of other spools. 3D Mars measures 67x200mm while eSun is 62x200mm. If you're using larger spools, then you'll need a larger container - in which case my 3D printed parts will work just as well. The goal is to make the container as small as possible to avoid dead air space. What's the difference? Well, Zylar containers cost about 40% more and aren't sold at discount stores like Wal Mart. The Zylar has better-quality plastic that's more flexible, clear, and has a see-through lid. I'm not sure any of these qualities are necessary for this application - they seem to be made from the same injection machine, but the less expensive version is about 5mm shorter. This height difference means that V1.0 of the Filament SyStem won't fit. So, I've made minor design changes - you can use V2.0 with Zylar containers. There's no practical difference in the amount of desiccant space. With this version, I've added small detents on the cross bars that help with alignment for eSun and 3D Mars spools. The crossbars have eSun and 3D Mars added to their names - regular crossbars are also included. There are pictures of the filament end being placed into the hollow nut and then placed into the spool holder - I hope this explains how to use this option.
