Sovol Zero Top Back Vent

I wanted a way to print PLA without having the door open or the chamber fan blasting a full power. Also, I didn't want to take the top off to keep the noise down a bit. So, I created this to allow the hot air to escape while still providing a bit of noise relief.It requires 2mm pins to swivel the shelf around (https://www.amazon.com/dp/B0BCFH7NPJ for example). It bolts on to the top two back panel bolts. You can reuse the existing bolts if you push a bit. build by Duane
