Roller Blind Gear Wheel

thingiverse

Here is a replacement roller blind gear I designed because I couldn't locate a suitable replacement one. With the original, pulling up the blind consistently resulted in the blind cord slipping due to worn teeth. I've included a photo of the original wheel along with its measurements below: The cord's balls are 4.5 mm in diameter and spaced 6.3 mm apart 38.5 mm is the overall outer diameter 32.8 mm is the outer gear diameter I printed it in PLA with 100% infill at a 0.3mm layer height on the Ender 3 without any problems. I hope you find this helpful.
