IKEA Trofast Drawer Rail

I searched for Rail to mount a Trofast Drawer from IKEA in one of my shelves but didn't found the correct one for my needs.So I designed my own Version to use a Trofast drawer as a poop chute.The Trofast Drawer I used is the smallest one but you can use it with every version/size of it.Length of the rails is 28cm. in the pictures you can see how I combined it with a poop tunnel I found on printables.comhttps://www.printables.com/de/model/735220 (link to the poop tunnel file) It's printed with a Layer height of 0.20mm, 0.40 Nozzle and 15% infill with the standard infill pattern.I used eSUN PLA+ for it and it worked great.
