Pegboard hooks - Eurolochung - 15mm spacing, 5mm holes

Those are some hooks I designed (with a pretty clean customizable scad-file) for my pegboard with "Eurolochung", holes are spaced 15mm apart from each other in each direction, and the holes have a diameter of 5mm. (My hooks have a diameter of 4.4mm and fit perfectly with the slight angle in them).
