Cruiser Mk.V Covenanter (1:100, 15mm)
The Covenanter was the direct ancestor of the famous British Crusader tank of WWII. Its rushed production, initial teething troubles and opposition in certain official quarters gave it a poor reputation, though in truth by the time the Crusader came to replace it, most of those problems had been resolved. Nevertheless, though a few were sent out to the desert, it never did see active service. It did do excellent service as a training tank in the UK though.
This model is designed for FDM printing, and the zip file contains both turret and hull in either one-piece STLs, or split-up models to be printed and then glued together. My experience has been that the split versions will return smoother results on the sloping panels, and better detail in the tracks.
