This is a remix, designed from scratch, of the great model created by Billie Palmer. It has the following differences:

• Made it longer, to better support small spools.
• Added a long support at the bottom side, which touches the bottom of the AMS and stabilizes the adapter.
• Hollowed the body to use less material and speed the print up.
• Used a few 45 degree walls so no support is required.

I've been using it with 16cm spools but it should work with other sizes (let us know in the comments).

Printing

• Position it as in the STL.
• PLA or whichever other material.
• Default Bambu Studio presets work great.
• The two front bits touching the bed may have a hard time with the printer speeds. You may want to use brim.

Installation

• Remove the back roller from the AMS slot you want to use. You may insert a plastic lever under it to help.
• Turn the adapter print upside down.
• Insert the removed roller into the two front hooks.
• Insert the adapter back-bump in the AMS inside the slot you removed the original roller from.

You can now load small spools just like the other ones.

Enjoy it!
