Add-On Knob for DB-9/15/25/37 Attachment backshell screws

thingiverse

Remixed from a Remix by ElizabethGreene. Her tiny screwdriver bit handles were downsized to fit on DB-9/15/25/37 backshell attachment screws. Nothing fancy, just a straight scaling of her redesign. But they work perfectly to make these easier to access and manipulate when installed in electronic devices, like my airplane panel. No tools needed. The tiny little screws (First photo) that come with these shells are very difficult to work with, especially when you can't see them. They are easily replaced by longer knurled screws (2nd photo), but even those can be hard to work with when invisible behind a panel. These knobs make the longer ones MUCH easier to grip and turn. The hole doesn't fit as printed, which is fine. I wanted to make sure they wouldn't come off, so basically, you just heat the screw shaft with a lighter/heat gun, and press it into the little handles, and then it isn't going to come loose. If you MUST remove them, just re-heat, and they'll slip off, but then you have a bit of cleanup to do.
