Kickdown door stopper

A foot operated door stopper.
It has 2 magnets to keep it in upright position.
There's a foot pad to drop it down and there are spikes on the end of the foot so it stops well on thick carpet.

Additional parts required:

-m5 (or similar) bolt/thread and nut(s), for the hinge.

-6mm diameter round magnets, 1mm-2mm thick.

-4 small screws to attach it to the door (glue or double sided tape probably works too)
