Update 12/19/22: Added version for 3-prong plugs (NEMA 5-15)

Update 12/19/22: Added version for plugs with a larger neutral blade (polarized plug).

My new laptop travel charger cable came with a prong protector but I kept misplacing it. So I reversed engineered it and added a strap that clips to the cable. It is sized for the common flat style of cables (6.8mm x 4mm or 5/32'' x 17/64''). STEP and Fusion 360 F3D file included so you can modify the clip if it doesn't fit your specific cable.

I printed it with translucent PETG, at 0.2mm layer height, 3 perimeters, 15% gyroid infill. Any flexible material should do (PLA, TPU etc).
