Wooden slat/shutter guide.

A friend of mine bought some slats without guides, that he wanted to be opened 6 -10 at a time. Made this simple guide rail, which works wonders. Distance from hole to hole is 50mm. Model consists of a right 3 hole piece, a lefte 3 hole piece and a 4 hole piece which can be connecten with the small brick/connector. A bit of glue would hold it to getter perfectly altough it already a tight fit from itself. The hole is 3mm which fits m2 and smaller m3 screws.
