Bambu Lab Manual Material System

What you call this mod is up to you. 
-Manual material system
-AMS ultra lite
-Botch and fumble AMS

With this mod you can print up to three different filaments.

Only the rear holder with the ptfe hose needs to be replaced with the mod.
Unfortunately I only have 3 10mm connectors and one 6mm connector. Therefore the hole diameters in the model are different. You can adjust the diameters in the step file according to your needs.
I clamped a small piece of ptfe tubing to each of the three inputs to hold the unused filaments. This way, when changing filaments, you only have to pull back the current filament after cutting and push the next filament through to the hotend.

You do more or less the same as an AMS. You are the AMS!

In order to use the slicer correctly, like an AMS, you have to change the filamentchange gcode in the printer settings.
The corresponding g-code is in "noAMS.txt".

I tested it with Orca Slicer 1.6.6 on my P1P with firmware v1.02.02.00.
It should be compatible with other versions as well.
Use it on your own risk.
