I love my Baby Joy Crib specially because it helps my son get up. The height of the rim makes it easy to pull himself up.

Now, the problem is that the crib is too high and the risk of getting hurt is too much. So we decided to remove the lower legs.

Two problems arise: 1) If he leans on one side, the crib will tip over (happened to us),  also if he grabs onto something it gets even worse 2) We have hardwood floors, and the raw metal edge of the legs will scratch the floor. 

These Shoes, solve both problems... we tested it. 

It needs no supports. It is meant to be printed with PETG or any other rigid material. Don't use flexibles. It has a hole for a screw to hold it in place #6 wood.
