Saturn 2 magnetic vent access cover

I use the vent system created by @Ghengisahn_411714 for my Saturn 2, but I wanted a way to close up the cover for occasions when I didn't have the hose attached. As a result, I created this solid panel that works with the magnetic system that's already in place. 

You'll need 4 12x3 mm magnets. Make sure to check the polarity before you glue anything in!

The settings and materials shouldn't matter much, just print so the recesses for the magnets are pointing upwards and you won't need supports. Happy printing!
