I Made seat back adjuatment knob. The majority of my seats have broken or missing seatback angle adjustment knobs, and I didn't really want to spend $50+ to replace them. I could not find a 3D printed version, so I spent a few hours modeling and prototyping one. I have not torture tested it yet, but I have printed 2 and installed them in my 76' that I am rebuilding. they feel pretty sturdy and work for now. I'll see how they do over time, but if anyone is printing ABS or otherwise, they would probably hold up well. I made them a little beefier than stock, but not larger overall.
adjustment knob to replace broken knobs on Volvo 200 series cars, including 240, 242, 244, 245. may be compatible with other models. This knob attaches just like the original, simply press it into place on the keyed plate so that the notches are engaged. the fit should be snug enough to hold...
