Using the External spool in my print room just became more convinient. With this remixed Bambu Labs AMS Lite PTFE tube support the external spool can share a path with slot 1. Manual loading and unloading is still required and the AMS slot 1 must be unloaded before the external spool can be loaded and vise-versa.
With this set up your PTFE will have less wear shoving them in and out of the hub and it is just more convenient.
The PTFE are pressure fit into the bracket and are seated 6mm. A piece of tube 46mm long is required for the cuopler to the printed component.
