IKEA Billy Double peg support

A support for the shelving on a IKEA Billy bookcase that takes up two peg holes and provides extra support. The bookcase I use for holding my games consoles is bowed with age and the gap between shelf and bookcase is dangerously large. If pushed the shelf has been known to collapse. Four of these give the shelf extra support and make the whole thing a lot less precarious.

STL and OpenSCAD files are included. The STL file should be read in using a millimetre scale to get the right sizing. Print with the pegs uppermost, for me this required a 180 degree rotation around the Y axis
