Something I put together quickly to hold my stud finder on some peg board. The holes are spaced so that they should line up - I intend to put some drywall plugs into the holes and screw this to the board for a sturdier mount. Of course, it could also just be screwed or nailed to a wall. I printed it and it fits the tool very well, but I have not yet mounted it.

I plan to modify this again to thicken up some areas to be a bit stronger, but it should be alright as is for such a light weight tool.
