["Open Source"] JAYO Plastic Filament Spool AMS Adapter Ring

I tried several community models, but the results weren't ideal, so I made my own.

I personally 3D printed and tested this about ten times. The model's dimensions are based on my own precise testing; however, since the actual printed dimensions may vary, I'm open-sourcing the model so that you can fine-tune it if necessary.

Note: After installation, the finished product shouldn't be too tight; some looseness is preferable. The two locking pins at the JAYO logo control slippage.

Feature Overview

• The outer ring measures 200mm after installation, adhering to the AMS factory standard.
• Wider sides increase the friction surface, reducing slippage during rotation.
• A full ring clasp design eliminates the need for supports. A slight gap is maintained on the ring surface to prevent deformation upon fastening, which would reduce the side friction area.
• Rounded edges on the exterior and a dedicated area to "hide" the Z-seam reduce the protrusion of the Z-seam and subsequent wear on the AMS retraction shaft.

Printing Recommendations

• It is recommended to use PETG or other higher-strength materials for enhanced durability.
• A 0.2MM layer height is suggested, with 3 walls and using the Arachne wall generator. Iron the top surface, and the seam position must be set to aligned.
• 100% infill is recommended.

• Supports are not required.
