This is a remix of Bambu AMS Feeder PFTE Adapter by ktothestank, big thank you to them for their design.

The purpose of this is to clip on to the top of your Bambu AMS Feeder Tubes, to protect it from wear from abrasive filaments (glow, carbon fiber, silk, wood fill, etc). On the facebook groups we can see the feeders getting worn down very quickly after only a few rolls of abrasive filaments - Bambu Lab really should have made these out of metal, but oh well.

What's new in this remix:

• Slimmed down the part and beveled it on the side facing the spool of filament, because I found it to be rubbing and binding on some spools that were full of filament.
• Added a circular pattern to the top to assist in sliding the mechanism forward.
• Orient model correctly for printing.
• Remove bevel and re-make design of tubed version.
• And more…

That's it! Over time, I may make additional improvements if necessary.

Versions:

• Tubed version for using PTFE tube. I recommend this version. The tubed version is designed for most PTFE tubes with 4mm diameter, perfect fit for the Bambu tubes. May not work with Capricorn tubing, but why waste expensive Capricorn tubing on this - LOL.
• Tubeless version if you do not want to use PTFE tube; the parts may wear down over time and can cause filament dust to build up in the AMS system requiring a cleaning.

Printing instructions:

• Print at 0.16mm layer height, you will need 4 of these for every AMS you have.
• Print at normal speed, default Bambu settings.
• Print with any material of your choice (I did PLA).
• I personally used the Bambu Studio and AMS with two filaments to color-in the circle and make it look nicer.

Installation instructions:

• These are supposed to be a very tight fit, so they don't come off on their own once on.
• If your printer is not tuned well and using high quality filament, they may actually print too tight or loose. Be sure to calibrate your flow rate and everything before printing! Bambu X1 Lidar DOES NOT actually calibrate flow rate, only pressure and linear advance even though they call it “flow calibration”.
• Snap them on top of the gray plastic feeders in the AMS; it's a tight fit, so the best way to do this is tilting them to the side and rock it back level while pushing down.
• Do not install by pushing them straight down first. You must tilt them sideways onto the gray AMS feeders, you notice under this printed part is a “lip”, you want to slide this lip under the feeder on one side first before snapping the part down.
• If using tubed version, cut PTFE tubes for each (about 50mm / 1 inch should be enough for each piece) and push in and down.
• In the newest tubed version, the hole for the tube is intentionally a tight fit to prevent the tube from sliding during printing. If you cannot get your PTFE tube to fit, you can use a small drill bit and widen the hole just a little bit if you need to. My Bambu PTFE tubes fit very tightly, but I was able to get them pushed in by hand without modifying the part after printing. If you are using other brand PTFE tube, your mileage may vary.

Design history:

• 12/12/22 - Added V3 of the tubed version. In this version, I have completely eliminated the unnecessary bevel on the top (not needed for tubed version), made the tube path at a slight angle that points towards the spool, and also shrunk the design size of the tube path from 4.25mm to 4.10mm to make the PTFE tube a tighter fit with less movement. Depending on the tolerance of your PTFE tube, it may be a very tight fit.
