ARC DESIGN! This arc design is a simple model and simple install and is a very effective in helping to reduce the likihood filament feed and pullback errors. This is not an overly complicated solution for the AMS internal hub! It doesn't require screwing something into place that could potentially damage your very expensive AMS! No screws required! It's critical the AMS internal PTFE hub function as designed without interference. This solution attaches only to the PTFE tubes improving and maintaining proper alignment of the PTFE tubes, at a consistent and specific distance from the hub, for smooth filament feeding and pull back! Simple design, print, and results.&nbsp;Check Out User Reivews and Feedback&nbsp;Simple To Print And Install:Simple to print and install. Don't be fearful of the install if you haven't yet dissembled your AMS. BL has an excellent and simple Wiki on this process. See Installation Procedure below.&nbsp;&nbsp;SEE INSTALLATION PROCEDURE BELOW <a target="_blank" href="https://makerworld.com/en/u/1072890529" rel="nofollow noopener">CLICK HERE TO CHECK OUT THESE OTHER PTFE ACCESSORIES</a>&nbsp;INSTALLATION PROCEDURE <a target="_blank" href="https://wiki.bambulab.com/en/x1/maintenance/replace-filament-hub" rel="nofollow noopener">https://wiki.bambulab.com/en/x1/maintenance/replace-filament-hub</a> NOTE: You do not have to remove the AMS Internal Hub. You only need to separate the AMS enclosure from the Spool Roller Assembly.&nbsp;Once you have the AMS disassembled it will look like this: <figure class="image"><img src="https://makerworld.bblmw.com/makerworld/draft/388682/2023-10-28_16513408f15088.jpg"></figure>&nbsp;&nbsp;The next step is to remove the PTFE tubes from the AMS Internal Hub:&nbsp;<figure class="image"><img src="https://makerworld.bblmw.com/makerworld/draft/388682/2023-10-28_a3bae2917401e8.jpg"></figure>Once the PTFE tubes have been removed from the Hub, install the AMS Filament Pull Back Guide on each tube. Move it up higher than needed initially<figure class="image"><img src="https://makerworld.bblmw.com/makerworld/draft/388682/2023-10-28_01acb3f912e128.jpg"></figure>&nbsp;After all the PTFE tubes have been installed in the AMS Filament Pull Back Guide, reinstall the PTFE tubes into the Hub and move the AMS Filament Pull Back Fix as seen in this photo:&nbsp;<figure class="image"><img src="https://makerworld.bblmw.com/makerworld/draft/388682/2023-10-28_3901d04a158868.jpg"></figure>&nbsp;Assemble the AMS in the reverse order you followed to disassemble it. NOTE: Remember to plug in the electrical connectors or you'll have to repeat the disassembly and reassembly procedure, which could be frustrating. Don't ask me how I know. ;-) That's It!

Edit: V2.1 expanded the opening for the screw head clearance Edit: V2.0 I added a new stl with a cut out for the screw head. I have not printed it out or tested it yetEdit: added a short version of the mounting arm to move the spool further back&nbsp;A quick and dirty mesh mixer remix I made combining two models to make the ultimate side spool holder.
