DIO remote magnet case

This a case to hold and protect a DIO remote (1 channel model 54791). I have design this to stick the remote on my fridge. The magnet has to be inserted from inside the case, and there is 2 layers of plastic to protect the surface (because the magnet can scratch the surface if it is directly in contact with it).

The magnet size to use is a circular 18mm X 5mm. I have provided the source file to let you adapt to your magnet size.

You must use TPU or other flexible material.
You also should use support interface to get a perfect shape inside the case once removed.

Please let me know what you think about it, and show me your makes :)
