Quick Draw magnetic gun mount
thingiverse
I preferred all of the rapid draw gun mounts available but they all seemed too pricey for a piece of plastic. Here is my take on it. It employs two 1" x 3/8" earth magnets to secure the gun. Linked below are the magnets I used: twelve for fourteen dollars means you can have six of these for less than it costs to purchase one from an online retailer. The magnets come with some stainless screws that work perfectly to mount them. You'll only have enough screws to mount three of them but additional screws can be found at your local hardware store for a couple bucks.
