Centering Discs for Bambu Spool Switcher & Winder

Here are several additional centering discs for Miklos Kiszely's excellent spool switcher and winder for respooling filament to fit the Bambu Lab AMS unit.

I mainly designed these for some empty spools I have that have a recessed center section. The discs included in Miklos' package are too small in the outer diameter and don't extend far enough into the center to reach the core walls. My recessed spools are mostly older Inland brand and work best with a 52mm inner diameter and need about a 100mm outer diameter to cover the recessed section. I know other manufacturers have spools with a similar recess.

I decided to whip up a quick design in Fusion 360, matching the original discs, but adding user parameters to make it easy to change the various diameters, wall thicknesses, etc. You can easily create your own custom disc sizes using my included Fusion 360 design file.

I also added a text profile into the design that is engraved into the disc to make it easier to identify the size. If you prefer to scale the discs in the slicer, I have included some blank discs so you can scale and add text using the tools in the slicer. However, using Fusion 360 to scale your discs will give the best result by keeping wall thicknesses and the center diameter consistent.

Let me know if you have questions. Enjoy!
