Costco (Whalen) Shelf Boots (floor protectors)

I modified this great design just a bit to add chamfers on the inside corners to make sure it was strong enough. I also decreased the thickness of the base to 2mm and print it with 100% infill. I chamfered some more edges to reduce material, and made some internal changes to increase internal walls for more strength. 

Protect your floors and make it easier to move your racks around.

The metal feet on these Costco / Whalen storage racks are better than some, but they can still scratch, dig into, or catch on wood, vinyl, or epoxy floors. These 3D printable caps slide onto the bottom of each rack leg, spreading out the load and giving you a smooth surface that glides instead of gouges.

Included files:

• Single leg cap: fits one rack leg
• Double leg cap: spans two rack legs when you have storage racks placed side by side
