Bambu Reusable Spool - A1 Mini Compatible

About: This remix, most importantly, gives purely A1 Mini users the ability to print their own replacement spools with the small machine. In doing this, a square design was used to fit just inside the build volume, allowing for a proper spool, but fitting in the smaller space. Some other changes to this model are: Changed the six filament holders to four, on per corner. Used a less dense hexagon mesh for the side to allow for faster printing with strength. Adjusted the placement of the filament info tag, though still allowing for its use. Disclaimer: Due to its square shape, this spool will not work very well, or at all, on any spool holder that uses rollers on the outside rim of the spool, such as the Bambulab AMS (not AMS Lite, like with the A1's) and other roller-style holders. Though, any spool holders that go through the middle of the spool will function like normal, this as well goes for the AMS Lite. Enjoy!
