A quick model up of a 30degree angled HD camera mount for the Xhover MXP200B frame.
Haven't printed just yet, but will do soon and post actual images :)

I went with 30degree as it's pretty run-of-the-mill. If you want any other angles, just drop a comment and i'll see what I can do :)

Update: 24/03/2017 - Added two edited files; one with recessed screw holes; one with recessed screw holes, and antenna mounts (designed for 3mm antenna straws).

0.15

40% Cubic minimum

I'd suggest printing around 0.15mm layers (0.1mm if you don't mind the extra time) for best strength. Printing with 40% cubic infill and triple walls (1.2mm wall with a 0.4mm nozzle) should provide enough strength for general abuse, without being too heavy.
Rafts/brim as you see fit - supports required/recommended due to the velcro gap on the underside of the part (if your printer can bridge 25mm, then skip the supports ;) )
