85mm vent exhaust flange - Updated

Need to vent my laser cutter outside.

With protective grid to keep away those pesky X-Wings. (Stick that in your pipe and smoke it, Tarkin).

Originally the flange was 100mm*100mm but I thought it might be good to have it be able to be put in series with a 92mm fan so I adjusted it.

Updated to strengthen and to slightly reduce diameter.
