Made this after not finding what I needed either on Amazon or here on Thingiverse. I designed this to raise furniture with a leg base no larger than 1-5/8" in order to keep my Roomba from getting stuck. These pucks raise the furniture by 3/4" but can be easily modified for your required size.
Printed mine in PLA using 3 top/bottom layers, 0.20 layer height and 20% infill. You may need more infill based on the weight and number of legs your furniture has. My couch had 10!
