jetpack vent supplier?

After several years I am finely doing my MOW jetpack. In the past I bought a lasercut vent for the bottom. I glued it to the bottom than looked at reference PICS and I have found the vents are cut the wrong way. They are vertical instead of horizontal. Can't remember who I bought it from, but it irks me that people make runs of Fett stuff and don't look at reference. To be honest, I probably should have too before buying it.

So, I took it off and need a NEW CORRECT vent to cover the hole in my pack. Anyone know who makes or could make the correct vents? Help a brother out.
