The original version from JamesHartman fits nicely but my wife complaints that it slips. It may be due to the TPU 95A filament I used is not soft enough. I modified it to fit two TPU "rubber" bands that increase the friction both on the plug and on the fingers.

Note that the two rubber bands will be much easier to put in place if you put them on the cable before putting on the jacket.

Print with flexible material like TPU.

Recommend to print one "rubber" band for test first. If it is too tight, scale the X and Y in your slicer but do not scale Z.
