Filament System (1kg Spool Guide & Cover)

thingiverse

This is my ultimate Kossel Mini spool guide and protection system. The design, though not hermetically sealed, effectively safeguards your filament against dust, moisture, and sunlight. It can carry 1kg spools. I divided it into eight pieces to reduce the required printing radius and height to 130mm. This includes a part to observe the spool in motion and gauge how much filament is remaining (spool_window_corner.stl). A flat transparent plastic window closes the gap. Another component (spool_motor_corner.stl) is utilized to mount the system close to the bowden extruder. The assembly can be secured with M3 screws and nuts or glued together. I recommend sealing it with acrylic silicone for added protection. The spool_bearing.stl utilizes M5 screws to fix the bearing in place. To enhance the bottom part, I designed a new component (spool_filament.stl) that provides a smooth intersection with the extruder. I also improved the fila_cover.stl to close gaps and fit with the new bottom part. For the overall "ring" assembly, I created two new parts (spool_support_closedv1.stl, spool_support_closedv2.stl) to eliminate open gaps. The remaining temporary spool_support.stl components will be replaced. In a later update, I designed the floor_.stl to close the bottom of the system. This is no longer considered Work-In-Progress as it functions smoothly. To ensure the fixing nuts (eight pieces) remain securely in place, I recommend applying acrylic silicone to seal them. This prevents any risk of them falling into the assembly or onto the PCB when loose. For added convenience, you can remove the cover from time to time without worrying about losing the nuts. In a separate project, I designed a lighting system for my Delta printer, which includes an indicator light for my filament supply system. You can find this design on Thingiverse under https://www.thingiverse.com/thing:3086797. To enhance the look and seal of my windows, I created cover parts that you can search for under "spool bottom and top window cover files." Enjoy sharing your MAKEs and don't forget to leave a comment if you have a perfect printer. If so, I'll create the 45° version of spool_filament_corner.stl specifically for you.
