Bambu Lab P1 / X1 / X1C / X1CC Filament Spool Switcher & Winder - Heavy Load Parts.

Based on the feedbacks, it was designed and published an alternative drive to the model. This should also work with heavier spools. (but more than 1kg is not recommended) Please remember, it's always a plastic construction: don't run it too fast (frictional heat - will melt)... 3 minutes per kg should be a good result anyway. In this example: 1 kg PETG in less than 3 minutes (I respool it back and forth several times from a foreign spool to BBL and back, this is part of the recordings)
