Got a dog and picked up some simple stainless steel food/water bowls. Decided a device for the bowls to be held in place would be good, but didn't want to buy a whole new thing, so made my own. Initially made the holes for the bowls a little too large, so made rings to hold them better as well as raise them up a little to make them easier to remove from the platform.
Each half prints on a prusaMk3 plate. Use m3x16 (or so) socket head cap screws to connect the two halves. A little glue in between is a good idea, too.
To add some anti-slip feet, print the "feet" of the platform with no top layers, then drizzle in some flowable silicone sealant (found at auto parts stores). This can be tricky, because you have to put the same amount on each foot, so best to try and keep it level with the print, rather than make a tape wall like I did.
Use the 3mf files if you have PrusaSlicer and I've already done the work for you. Otherwise, use the STLs and do it yourself.
