Super Duster (for 6x3mm magnets) - Filament Guide and Dust Filter

⚠️ If you have other magnet sizes:

• Super Duster for 6x2mm Neodim magnets.
• Super Duster for 5x3mm Neodim magnets.
• Super Duster for 5x2mm Neodim magnets.

I wanted to design a suitable filament guide for my AMS protectors to prevent the almost empty spools from jumping around and at the same time I wanted to solve another problem - cleaning the filament from dust, right before the first introduction to the filament guide system. Many users store their filaments openly and they tend to attract dust, and the cheaper filaments in particular often come from the factory already very dusty. This will lead to problems with the AMS/hub or extruder later.

Super Duster can be attached to any 3D-Printer with PTFE tube guide!

The Super Duster is an “easy-print-in-place design” and only requires 4 magnets and 2 pieces (10x15mm) of a sponge cloth to keep the filament dust-free. Optionally, I highly recommend using two 4mm steel balls per Super Duster to minimize friction and smoother movement on the spool.

About PTFE tubing length:

My tests with my AMS protectors have shown that about 100mm length is good for keeping the almost empty filament spools from jumping around. But I would still recommend the Spool-Weights (such as one of these - I❤️this design from @humebeam). The filament spools are very different and only with such a Spool-Weight good filament processing can be guaranteed until the end of the filament on the spool.

If you only want to use the dust filter function (if you always use spool weights), then PTFE tubing piece can also be shorter (around 60mm).

Print Instructions (or just use one of my print-profiles!😍)

• first layer line width: 0.47mm (0.4 mm Nozzle) (for perfect look of the “face”)
• first layer speed: 10ms per second (for perfect look of the bambu-logo)
• first layer infill: 50ms per second
• top surface: 0.38mm
• 2 perimeter, 5 top, 3 bottom layer, 15% infill
• print layer height: 0.2mm
• WALL generator: Arachne

Sources of hardware:

Sponge Cloths (they should be about 5mm thick) - one piece would be more than enough! 😉
