I wouild like to add an overflow cover and have 3d printing capability, just dont want to re-invent the wheel if someone has created one already. This is for Oceanic/Aqueon mega overflow (150 Gallon) not the corner kind, the 10.5" wide kind. I know I can buy 2 off ebay or etsy, but hard to sell when I can print for a few $ and they want $20 each plus shipping. Dont mind giving a few $$ for the .stl file for your time. Thanks
