TTY3D Cardboard Spool Adapter for Bambu Lab AMS

A remix of Polymaker's excellent minimalist design for their spools. I wanted something that fit the exact same way, but for the smaller TTY3D spools which completely refused to work in my AMS unit.

Other changes from the Polymaker version are the replacement of their logo with 3 spokes and a smaller locating peg at the center of the spool to fit the smaller hole on the TTY3D spools.
