great silicone mat holder for those that use them for lots of baking.

I got a Cooler Master QUBE 540 case because it could be used on its side. but did not come with feet to use on its side. it showed some optional ones in the manual. I decided to make my own and this was the result. print easily enough, have a large contact area with the case to spread the weight out, locating pin to prevent them from spinning and they snap in to the round holes of the case.(Edited)

I found it annoying to get light decora light switches lined up. if your spacing is wrong the cover plate does not fit right. you never have to worry about tight fitting covers affecting switch operation. this tool aligns the switches to each other for perfect spacing while still allowing you access to the screws to tighten in place. optional level to help make them straight but just eyeballing it works great.
