Ikea LACK Castor wheel attachments

I wanted to add castors to my IKEA lack table but didn't like the ones that I found; so I ended up remixing this model with another lack castor attachment to allow for the solution you see now which is the best of both worlds.Measurement for hole :7.8mm hole worked for my castor wheels Link to the wheels that I used : https://www.homedepot.com/p/Everbilt-2-in-Black-Hard-Rubber-and-Steel-Swivel-Threaded-Stem-Caster-with-80-lb-Load-Rating-2-Pack-49344/203661048The instructions :Just use a hammer to knock out the lightly glued wood at the bottom of the lack leg and use pliers to pull out the wood.Then put the castor attachment in, while it's held in by gravity, I used some glue while putting weight on it to make it permanent.
