The bifold door kept falling and injuring a housemate. The broken part (foreground of photo) is probably from 1962, when the house was built. It doesn't have a part number. We don't know the manufacturer. Even if we did, we don't know if the company is even still around, let alone selling replacement parts.
So I modeled a replacement and printed it. About 90 minutes later (one print), and the door is fixed.
Tolerances were off, but redrilling the vertical hole fixed that and I fixed the model to match what worked in practice. #3Dprinting #DIY
