Just what everyone wasn't clamoring for-another cable holder.
I couldn't find a decent cable holder that actually held a USB-C cable. This holder makes it easy to drop the cable in and it won't let the plug twist and slide out. Scale this down a bit if you want to try for an Apple cable holder, but I haven't tried that yet, so good luck if you do.
Be mindful of whether this is going to take any strain (are you rough with your cables?) during use. If you print it on its side, that would probably be the best for strength, but you'll need supports. I printed it upright-no supports needed-so the layers are horizontal, so I just need to not rip the cable forward.
