Hey, I have something for this thread. Its not a big deal but I hope others can use it. I always have trouble moving the pins around on the floor, so I got those little mini-dollies from Harbor Freight: https://www.harborfreight.com/material-handling/hand-trucks-carts-dollies/dollies/3-wheel-steel-dolly-63683.html

While they technically worked, in my case the legs always popped off after just a couple of feet of travel. They really need deeper cups so the cabinet legs won't come off. So I ran down to the hardware store and bought a set of the largest PVC caps they had (2",) drilled a hole in them and bolted them on.with a 2: pvc pipe cap attached
Sadly, 2" caps are just a bit too small and the legs won't quite fit in them. I checked on the 3" caps but they are $10 each so I went to the dollar store and bought 4 sets of measuring cups. I cut off the handle of the 1-cup cup and bolted it on.with a 1" measuring cup
Its actually a bit too big, so I have switched to the 1/2" cups and they seem to be fine. Grand total: $20 for the dollies and $4 for the cups!with a 1/2" cup
