I made an angle bracket to be mounted on an ikea furniture.
The spacing between the pins and the screw hole is the standard 32mm. You'll need a standard "euro screw" (see picture).
You can adapt it on any pre-drilled furniture with Ø5mm holes and 32mm spacing.
10% infill is enough for now to support a 710x570x15mm wood plank and my anycubic mega-s.
