Antisplash for Sink

Household Item Problem: the silicone mat was suppose to drain spill water down the sink, but not effective.Solution: Design a customise mini wall to drain off spills using tinkercad. The white tabletop is 20mm thick. The top triangle design is 100mm(h) x 45mm (d) x 150mm(w).The pictures show 2x 3D print glued together forming a 300mm wall. As this is customise for my needs, feel free to use or create your own. Remember to put glue on the plate to prevent print slip though (due to print height).
