Bambu spool dimensions

I’m sure it’s been covered but in the few minutes I searched I couldn’t find what I was looking for. I am at work so it wasn’t my best search.

Also, due to the fact im at work, I can’t just check for myself.

Does anyone know what the inner diameter is of the cardboard center tube on Bambu filament refills?

I know the ID of a bambu spool is 55mm and the AMS lite works with spools 53-58mm.

This is more a question geared towards printing reusable spools, just looking for the cardboard part ID so I know which reusable spools are compatible with it.

The spool dimensions are approximately:

  • Width: ±67 mm
  • Outer Diameter: ±200 mm
  • Inner Diameter: ±55 mm

So does that mean the overall diameter is around 200 or 255mm?

Yeah I just gave up trying
