pool skimmer cover

Hi!I broke my skimmer cover so I drew another one and printed it. DimensionsOuter radius: 176 mmThickness where you put screws: 5 mmThickness whit supports: 11 mmFrom hole to hole: 160 mmI also put a step file so you can change it if the dimensions don't suit you.I printed it whit ABS, but PETG will be fine also.
