I wanted some screw caps that are reasonably soft, as I've scratched my head on a few, and lower profile than the standard ones available. I also found that the standard screw cap covers open with the slightest knock and the little hinge breaks easily. So I designed these. They offer the following:

• They are soft as they are printed using TPU
• They protrude 3mm, lower profile than the standard version
• Slightly rounded outer edge, I've yet to scratch my head (a year since fitting them).
• Don't have a hinge or opening tab. I've not had a cover come off.

Just place the screw through the screw cap and screw into position then push the cover into place.

If you need to remove the cover just use a pointed tool at the edge of the cover to prize it out.

I hope you find them useful.
