Got this VCR at a Goodwill. I tested it there and it seemed to work, but it turned out to have some trouble rewinding tapes. I opened it up and found a broken plastic piece, which I learned is the rewind brake. I'm still not sure if I broke that when I opened the VCR because after finding an STL for it (love this community) and replacing it, the VCR still wouldn't rewind reliably.

I did some further testing and found that the belt was slipping, so I started looking for a replacement—only to find that this particular VCR must not have sold well because I couldn't find a matching belt anywhere.

Luckily I had some TPU so after whipping up a belt STL (and cooking the filament for 2 hours at 55°C), I have a new belt and the VCR works perfectly!

If creating hard or impossible to find parts to fix obsolete tech isn't what 3D printing is all about, I don't know what is.
