This gun plate was designed to cover the forward-facing .303 machine gun housing on the Airfix 1/48 scale Anson. I don't think the Anson trainers in Canada were armed, so here is my quick fix.
 
(Of course, after I drafted, printed, and attached my plate, I found a photo that shows a better representation than I originally built. (as seen in my primed fuselage half.)
 
The fix is easy though. Before printing, reduce the "X" and "Y" scale by 30%. Also - the thickness is very thin and fragile after curing, so do not reduce the "Z" scale at this time, rather, after it is printed, sand it as thin as you need.
 
OMG..... OR..... You could simply use part #17 ?   IDK...

This is my first attempt at constructing a 3D model in a CAD program (don't ask how long this took, lol) It's not perfect by any means and I had to "scale" it one millimetre or two narrower before I printed it out.
 
(It is not permanently attached in this sample image - just placed)  Also, I cut the copilot seat apart (seat and backrest) and will glue this to the inside of the frame after it's painted black.
Lastly, I cut the copilot rudder bars, and re-attached them in the "stowed" position.
The "spare" control column will be hung on the rigging.

A pretty accurate mask (at least for my old tired eyes) for Cricket or Silhouette.
