Recently got a new MacBook Pro (2021) and noticed there was no good way to wrap the cord around the power brick. Naturally, I looked to see if there was anything already made for my charger (Model A2518). I couldn't find any that would fit. This charger seems fairly unique size-wise and also uses a Type-C connector. So, I just modeled one from scratch.
I wanted to improve on the other models I found, I wanted a way to stow the end of the cord so you don't have to tuck it under or anything. The end that goes into the MacBook is magnetic, so I chose to embed some 6x3mm magnets in three of the top corners. This allows the cord end to stay in place. You'll see the pockets in the slicing preview, just add a pause script before the top layers go down.
When wrapping, I've noticed you need to go clockwise (facing open end) in order for the laptop end to match up at the magnet in the lower left corner.
