Fits a piece of metal 45.2mm X 65.5mm. Snaps in if you pull the case around it a little. Made with Xyltec TPU 95A.
The case depth between the metal and the magnet is only .25mm to try to get as strong a hold with the magnet as possible.
The author remixed this model.
Just changed the shape and depth of the space for the metal to fit the piece I have.
