50mm vent for vivarium 5mm deep

thingiverse

A two-part vent use infill to determine vent hole size and shape print the outer ring as normal for the inner ring set to have no top or bottom layers and adjust the infill density to size hole required if you can print them both together it would be better set different processes for each part as shown in the screenshot designed slightly smaller for a 50mm hole in a glass panel if you require a different size just send a request and I will try and upload when I get time
