Requires Magnets with a 6mm diameter and 3mm thickness.
Moreover a M3x12 Screw (or longer) + M3-Nut is needed, that fixes the hinge of the MagSafe mount.
On the bottom there are 4 places for felt stickers (20mm diameter, 3mm thickness). But there's no need to install them.
For the orientation of the magnets refer to the model from Uko https://www.printables.com/model/47621-magsafe-wall-mount
The author remixed this model.
