YAFEH (Yet Another Friggin' Earphone Holder)
by 3d0g, published
Does Thingiverse really need another earphone holder? I'm afraid so. I've printed at least a dozen designs out there and they're either 1. Too small, 2. Too specific to a brand, or 3. Too fragile. So, I fired up Tinkercad and did my own design.
Easy to print, this holder should handle buds of any size, cords of any length (with or without controls) and should readily withstand your backpack.
Press-fit the bottom to the core (or glue if needed) and use a small screw to fasten the lid.
Just added a v2 of the bottom with a bit more reinforcement. Had one sleeve snap off during assembly.
