I made this thing to secure this ikea shelf to my wall because my floor is not flat and with the radiator pipes on the bottom of the wall, I couldn't use the aluminum brackets I already had.
When I was pulling stuff from the shelf, it was almost falling on me so I secured it to the wall with this bracket, there is no issues anymore.
It's very solid even tho it doesn't use lot of plastic and it's also beautiful with this honeycomb pattern that I like so much.
Dimensions are :
Top part : 10cm x 5cm
Wall part : 5cm x 5.5cm
For the screws, I used :
Top part : 3 * 3x40mm
Wall part : 1 * 4x80mm
Printed with FormFutura PLA Red 1.75mm
