IKEA Skadis continuous shelf

I made a continuous large 5" shelf with rib reinforcements for the medium size tech brick cars. Theres a left and right shelf with stoppers so that the kids dont roll them off to the floor, and you can print as many middle open shelf sections as you need. I have two wide skadis boards so about 6 or 7 middle sections. I also made some for the speed champs version at 3" wide with no reinforcements needed, which also work great for hotwheels.
