I needed a riser for the dog water bowl we use when we take our German Shepherds out to the yard to play. This was my solution. It was designed for a 7.25" to 7.5" bowl. This could easily be altered to fit another size bowl by adjusting the X and Y dimensions and the height can be altered by adjusting the Z dimension.

This was printed using PETG filament on a Creality K1Max, with three walls, four top and bottom layers, and 8% Gyroid infill. No supports were needed. Print time was about nine hours, using about 500g of filament.
