One of my Starions I adapted a 1G DSM MAF, the 1G MAF doesn't fit in the Starion aircan and the 1G air can doesn't fit nicely into the Starion, so I made an STL for an adapter to use a standard cone filter.
If anyone wants on you can download the STL from here https://www.thingiverse.com/thing:5801293
I used a truck cone filter. I didn't model the holes for the bolts. Just dab some paint on the MAF nuts to locate them and drilled the holes myself.
