Bambu Lab P1 / X1 / X1C / X1CC Filament Spool Switcher & Winder if you use AMS

Purely mechanically controlled filament winder for Bambu Lab P1, X1, X1C or X1CC 3D Printer.
Printed on Bambu Lab X1 CC.

The model is available for free download and use.
If you still want to invite me for a coffee for my effort, troubles and time (I ran out of filaments a couple of times), you can do it via:

Please use always bed leveling & flow calibration for this model, especially for the gears and axles!
Bambu Lab P1 should at least be calibrated. (linear advance)

As a source of ideas I used this great design (but everything was redrawn):
https://www.thingiverse.com/thing:5614035

I uploaded some print suggestions as *.3mf files.
(5 print plates for Bambu Lab / Bambu Studio with PEI plate @ the end of the list - attention, not cold plate)

Update:
I tested the "maschine" again and again and it happened to me too: the 45 mm axle (the driven one) broke!
The 3 walls and 25% infil are not enough!

If you haven't printed it yet or broke it, then please print it with:

0.16mm Optimal @BBL profile
5 or more wall loops
100% infill (sparse infill density)
Rectilinear (sparse infill pattern - set automatically)
speed outer wall (slow as possible for more accuracy) e.g. max 60 mm/s
support (yes) normal (auto)
