This model is designed to be a holder for two MagSafe chargers. The larger has diameter of 55.9mm and height of 5.37mm. The smaller has diameter of 28mm and height of 5.00mm. The cables route downward and to the back to come out parallel to one another. This is designed for a cable diameter of 3mm and should hold the cables in place. It may require pushing the cables past a small detent in the cable route to pop them into the appropriate groove.
This is designed to print without supports.
There are some tolerances built into the model for diameter of the chargers, height of the chargers and the cable routing is slightly oversized.
Enjoy!
