I made this riser for my 4.5 inch plastic pots that are a little to short for some ceramic pots that i bought. The riser is 4.5 inches in diameter and is 1.5 inches tall, but you can just scale the feet in the z direction to make them taller. I made it in two pieces so it can be made without supports and I added sufficient drain holes to let your pot drip through. Enjoy!
