My girlfriend snagged us a new CatGenie 120 AI cat box, and I needed to run the water and drain into our vanity in the bathroom. So I drilled a hole, measured twice, and designed a grommet to protect the cheap particle board from abrasions.
Made in Tinkercad, it is easy to print and useful if you remember to print it before you put the lines through the hole.
