Shades/blinds inner attachment piece

thingiverse

These little pieces break on the inside of our blinds all the time - it's the part that the strings on the blinds attach too. Don't know if they're brand specific or not. I print in PETG. No supports, just make sure to orient each piece with the flat side down and the little knob up. There's a bit of an overhang - the lip on the knob. It prints well enough for function.
