I was disappointed to find that the 2016 MacBook Pro's charging cable no longer had the two little clasps that would hold the cable when not in use. So, I made my own alternative.
This build has two main functions:
(1) Bundle the small USB-C wire when not in use.
(2) Keep the main charging unit supported and off the ground (in particular, carpet) when charging your laptop to permit better heat transfer.
I have iterated it a few times to get it to snap onto the charger without fracturing when made of PLA. I found that rotating it onto the charger is the best way to attach it.
I hope you enjoy, and don't forget to post photos of your makes.
