(4-in-1 Storage Box Version) 3D Filament Dehumidifying Dryer Box (Four Spool Positions) Simplified Version

I. This storage box can hold four filament spools, making it compact and efficient, however, the popular bases on the market often require 7-8 hours of printing, even with a successful first attempt. I experienced spaghetti two nights in a row, only succeeding on the third attempt, feeling that it was very time-consuming and wasteful of material. During use, I found that the printed bearings would quickly seize up, and the filament spool could still feed smoothly by directly sliding and rubbing against the support

Based on this situation, I removed the cumbersome base and bearings and placed the filament spools directly onto two stainless steel tubes, then used 5 supports to hold up the two stainless steel tubes. The base plate features a honeycomb grid pattern, securing the 5 supports, which not only saves printing time and filament but also serves as holes for molecular sieves

II. Parts List: 2 stainless steel tubes, 29.5cm long, 6mm outer diameter, 1mm wall thickness. You can just buy one meter

The vertical supports are in another one of my models, I'm currently not very good at uploading two models simultaneously, please find them yourself
