Print four of these to raise an Ikea Lack table the perfect height to make an enclosure for the new Creality Ender 3. (70mm). Shockingly, they fit perfectly for me on the first try! Slide right on, but just snug enough to not fall off when the table is turned right side up to stack it on the other table.
NOTE: The CR-10 and CR-10 Mini are taller than the Ender 3! I'm pretty sure you will be disappointed if you try to use these for a CR-10 enclosure!
