I design primarily for the Interwar and WWII periods, and in 1:100 scale for 15mm gaming.
These days I print models almost exclusively in resin, but wherever it is feasible I design with tolerances suitable for FDM as well.
The first of the Crusader line of British cruiser tanks.
The 1:100 scale (15mm) model is supplied in versions with or without wheel covers, with open or closed turret hatches, and with one-piece or two-piece turrets. You will have to provide your own commander figure if you want one.
