This is a near-exact replica of the cable clips included with my Schwinn Vantage F3 hybrid bike. It's probably not a universal design, but I expect it would work on other bike frames with similar cable guides. It only takes a gram or two of filament!

Any rigid filament should work. I've tested PLA, PLA+2.0, and PETG. If it's too tight, scale it up a bit on the X and Y axis.

Disclaimer: I didn't design this, I just scanned it with OpenSCAD Contour Scanner.
