fridge door guidance

The original fridge door guidance system, which came with my IKEA refridgerator, broke. Since one cannot buy this thing as a spare part I designed and printed one. The two pieces, "rail" and "cage", form a guidance/slide system for the IKEA fridge door and its front panel door. The rail (fridgeslide.4.stl) is screwed to the inside of the front panel door. The cage (fridgeslide-cage-1.6_konische-Schraubenkoepfe.stl), which will slide on the rail, is screwed to the outside of the fridge door. Open
