Ikea Billy Longboard Holder

A longboard holder system for the Ikea Billy bookcase. Made for 70mm wheels.

I've decived not to use any screws to fasten the holder. The board is held firmly using it's own weight. Though you might want to use a double-sided tape to prevent it from moving when the board is not mounted.

The bottom pieces are an optional, but useful addition imho, unless you like dirt on your bookcases :P
