Dishwasher Pipe Hole plug

I had to replace my dishwasher recently and chose a Bosch with an aquastop inlet valve. To fit it the existing pipe round hole in the cabinetry had to be enlarge to 100mm x 50mm to allow the passage of this cold water inlet valve through. Attached design is a plug to reduce (& neaten) the size of the hole after installation.

I printed in PETG though PLA or ABS could be used.

I made the plug exactly 50mm wide so you may need to adjust by scaling in your slicer to meet your needs
