I was using it for about 5 years myself and arguably it's the best 1.75mm filament clip ever been made.

It's easy and fast to print and require minimum of filament so you can print it using any tiny leftover bit

Settings are adapted to have best quality printing on Bambu lab printers

If you feel it's too tight or too loose - you can play with “scale” option in slicer settings
