Teeny Tiny Filament Clip

Did the world need another filament clip? Probably not. But did I make one anyway? Absolutely! This teeny tiny filament clip was more of a personal challenge to create the smallest, simplest clip possible—just for fun!
 

Most filament spools already have 6–7 mm holes to hold the filament end, but let’s be honest… they don’t always do a great job. This model slots right into those holes, forming a snug little opening to keep your filament in place and tangle-free.
 

Unfortunately, it won't work on Bambu Lab spools, since their 3 mm holes are just too tiny for sturdy pins, and it seems to work best on paper spools since they have enough flexibility to prevent the small pins from snapping.
 

So far, I’ve tested it on eSun, Overture, and Anycubic paper spools, and it works surprisingly well! Various sizes between 6 mm and 7 mm are available. Need a different size? Just let me know!
