Front side panel remix - remove danglingvent space

This is a remix of NovaNox's side panel, front portion: https://www.thingiverse.com/thing:2370329/

This is more for people using the remixed back panel from JCTots: https://www.thingiverse.com/thing:2451362

I just closed up the dangling size vent arms to improve strength. This is my seconds remix from a very noob skill level. (My first was a remix of JCTots side panel remix for fan mount)

Attached are the STL, OBJ and MeshMixer MIX files. Hopefully I didn't mess it up too bad.
