0x0029.3 - 1/2 yr Update on HP-86 3D Printed Key Stems

The 3D printed key stems on my HP-86 have held up pretty well over the last 6 months. But there are a couple problems to fix. First video in the series:    • 0x0029.1 - HP86 New 3D Printed Key Stems: ...   Key stem design files: https://github.com/AkBKukU/series80-t... I think these new parts will stand the test of time. Only a few stems had failed with the last batch. So fixing that minor problem will probably be it. These are still removable, not easily, but they are. I had to pull them out several times while going through this to re-file them to get all of the to work well.
