JustAnotherSpoolWinder (for BIG spools - 2.5 kg)

I bought several 2.5 kg filament spools, but they don’t fit into my spool dryer. When searching for a spool winder, I only found designs that either didn’t support large spools or required almost a full kilogram of filament to print.
 

That’s why I decided to create my own solution – and JustAnotherSpoolWinder was born.
 

The design is intentionally simple: no complicated gears, no unnecessary parts. It’s lightweight, functional, and works surprisingly well with large filament spools. Since it has been very useful for me, I wanted to share it with other makers.

You can transfer from the 2.5 kg spool to your regular 1 kg spool, without problems.
Any spool which has the Bambu Lab diameters should be fine, I used the following:

I recommend to use PETG for the first plate, everything else can be PLA. You might be able to also use PLA for the first plate, but I never tested that.

So, give it a try :)
