Shapeways has gone bankrupt. I think i spent $25.00 on a US market headset clip from them a few months ago. no more. Xometry and others are asking $80.00.
I took the .stl file and 3d printed 25 of these in PLA plastic.
Keep in mind this is a simplified version of the original version, it's also PLA plastic and not steel. equally, they both are small and get lost just the same.
It dropped in without any filing. looks decent and functions fine. Longevity will not be like the metal, but appears to work for now.
If you are an attention to detail person, this will work.
