I wanted to hang my golf trolley to the wall so I would have some more free floorspace in the shed. I designed the part so it doesn't need supports to print.
You can mount this part with bolts/screws to the wall ø4mm-6mm
2 holes are ø8mm in diameter

I myself used two ø4x40 mm screws in wood with washers to bridge the gap.
