Top Shelf Bracket

There are a lot of shelf brackets which support from below. For our washing machine I was looking for something which holds the shelf from the top, so I can mount it directly above the machine. And additionally it prevents stuff from falling behind the machine too easily. So I made this bracket for a 250x18mm plate which is very common in hardware stores.

Thickness is 5mm which gives enough stability for my use case, but I would not recommend to use it as a bookshelf. To avoid a gap between shelf and wall the edges need to be notched. The bottom part has two countersink holes for 3,5mm screws to secure the shelf and the back part has two 6mm holes for wall mount screws. I screwed it with 6x50mm screws and an M8 washer to the wall.

The gcode file is for MK4 with input shaping. For stability I printed it with 3 perimeters and 25% infill.
