Anycubic Mega S Spool Adapter

My design was inspired by https://www.thingiverse.com/thing:4051421 but I didn't want to drill holes in the stock spool holder. My design slips over it. Designed in Tinkercad. I've since found other slip-on spool extensions but I developed mine independently.

VER. 1.5 - 6/3/2020

Made adapter a bit rounder and wider to better stabilize narrow spools. Adjusted "slip-on" pocket to fit a bit tighter on the stock Mega S spool holder.
