Welcome fellow prototypers! This communities' purpose is to help others and share functional 3D Printing related information. While other 3D Printing Communities are a good resource, sometimes too many help posts get buried under memes and fluff. This will remain technically focused and keep the fluff removed. Please help your fellow 3D Printer hobbyists as much as you can with their issues! and showcase your functional prints and how you use or created them.
Designed an easy to print spool held together by M3 screws. No supports necessary. Master Spool standard.

You can't just go around calling yourself a master spool. You have to go through years of spool apprenticeship then serve as a journeyman spool before you can take the test to become a master spool.
