Made a screw in wall mount for the quite heavy power brick of my monitor (KTC M27T20) but I reckon other power bricks with a depth of 76mm and a height of 36mm could also be held up by this. 4mm screws go right in. I printed this in generic PLA with 20% triangle infill and it holds the weight well. Tried screwing it into the bamboo desk from IKEA but that didn't go well enough, but if your desk is made of better wood you could very well mount it with the screws from the back to make it part of your desk as opposed to stuck to a fixed point on the wall.
