Skateboard Wall Mount

I wanted to mount this longboard (without wheels) to the wall.

The board is fixed to the mount through M5 brass nuts (https://www.amazon.com/gp/product/B07H2RWRW4), which are inserted into the predefined holes with a soldering iron, and M5*16 steel screws (https://www.amazon.com/gp/product/B074Q4Z2C6).

The dimensions for the board holes are 1.625" and 2.125" (New School).

To improve:
- The long and round holes to be used to mount to the wall are a bit small and moving the screw to the wall is a bit tough to move. There is also an inset to hide the screws when fastened, but this si too small as well. It works, but it isn't ideal.
