Secure AMS Feed Saver & Smooth Fix - Not A Button

“Feeder Saver” - The AMS is an engineering marvel. However, the infamous feeder “button”, AKA Feed Funnel, has caused much concern when it comes to longevity. Simply put, it will wear on the edges of the feeder filament entry forcing a potentially expensive replacement of the AMS First Stage Feeder. My AMS “Feeder Saver” will not only protect you from this potentially expensive reality, it will also properly align the filament to reduce the likelihood of feed and pullback errors. All this for about a dollar in filament for a set of four!

NOTE:

• Desiccant Box Version: If you have desiccant boxes, I recommend the print profiles with the following in the title “NO Sides - Desiccant Box Compatible”
• The "NO Sides - Desiccant Box Compatible”" version is a sophisticated print.  Make sure you properly prepare your print plate.  This version was revised to eliminate the rounded sides for increased first layer area.  
• Hydra Mod Version: If you are using the Hydra Mod for your AMS, please use the Hydra Mod Print Profile

Features and Benefits

• Protects the feeder “button” from premature wear and replacement
• Snaps on securely using a wrap-around design - Will NOT come off during a print like some other feeder solutions
• Precision alignment of the filament from spool to feeder reduces friction and helps prevent the likelihood of feed and pullback errors
• Uses inexpensive PTFE used for protecting the “button” and the “Feeder Saver”
• Tested with full-size 1kg spools and 1/4kg spools full and near finished
• Simple install - SEE INSTALL VIDEO BELOW - no need to remove the AMS First Stage Feeder to install or remove
• Satisfying “snap-on” sound when installing giving you confidence it will not come off during a print

Comments From Users

“I tried many of these designs and discarded them all, this is the best I have come across and printed 16 of them for all 4 of my AMS's. Well done on this design its well thought out.”

“Great design!”

“fits perfectly, thank you very much”

Secure wrap-around snap-in-place design

Alignment guide reduces the likelihood of feed and pullback errors

INSTALLATION:

1. Installation is simple and does NOT require you to remove the AMS First Stage Feeder (feeder).
2. Simply slide the “Feeder Saver” over the feeder making sure the front of the “Feeder Saver” is set in place and flush with the front edge.
3. The sides of the “Feeder Saver” should be over the edges of the feeder.
4. Once the front of the “Feeder Saver” is properly aligned and in place, push on the back portion of the “Feeder Saver” until you hear the very
5. satisfying “Snap”.
6. Message me if you need an installation video.
