here is a super simple way to use those small ends of filament. If you wear dress shirts and dont like your collars curling up, the this is the print for you. I made a few sizes and made the raw files in both double and single pieces so you can print as little or as many as your plate will allow. This is not anything fancy, but it is one of those things you dont need untill you need them. So whay not print a few to have on hand. it is also a functional use of the filament ends. I'm guessing you can use type of filament except TPU since they hav eto be somewhat sturdy.

Print on your filament profile at standard or draft speed. No need to waste time with anything finer.

Pic with black collar stay is actually half black and half white. I ran out of one filament and continued with another. No wasted filament at all!
