IKEA Trofast Tray Rail

Sometimes IKEA boxes warp so much that they no longer fit the original furniture's rails and fall off.

This ready-to-glue rail will allow your boxes (containing an obscene amount of Lego) to slide more smoothly and prevent them from falling off...

You'll need two 215mm rails per side.

If you're the lucky owner of a RatRig v-Core 500, you can print them as a single piece. To do this, edit the FreeCAD file.
