4/26 Update

Improved bracket, added a buckle for reinforcement

===========

Background:

To meet the needs of both AMSlite and manual feed, or even dual AMSlite, the original feeder only has 4 paths, which is too few, so I needed to make a multi-way feeder myself

Previously, there were two versions of the feeder expansion solution

A1 6+5 Way Feeder from jianxuesheng2009 - MakerWorld

Bambu Lab 8-Way Feeder from jianxuesheng2009 - MakerWorld

Both use pneumatic connector solutions. Both are compromise solutions

Introduction
This time, I personally think it's a more perfect solution

1. Uses Bowden clamp solution, completely solves the weight issue. The volume can also be reduced to some extent
2. The feeder is expanded to 8 ports to accommodate two AMSlite units at once

Printing and Installation Steps

Testing

1. First, print the test model. Different materials and printers may have tolerances. The test part prints faster, allowing you to quickly determine if scaling up or down is needed before reprinting
2. Snap the Bowden collet into the test piece, try moving it back and forth. It's best if it moves just right. Not too loose or too tight
3. Insert the blue retaining clip
4. Insert the PTFE tube. At this point, the PTFE tube should be locked. Remove the blue retaining clip, press the Bowden collet, and the PTFE tube should be easily removed

Installation

1. Complete the Bowden collet installation for the feeder
2. Remove the official feeder; you can check the official wiki
3. Install the bracket first
4. Install the feeder
5. Insert the PTFE tube

Notes

1. Make sure to install the bracket first. If you install the feeder first, the bracket cannot be installed
2. The feeder is relatively fragile and easy to break; be careful during installation. Once installed, you don't need to worry
3. See figures for other details
