Saxon APC
Here's a 1/100 (15mm to wargamers) model of the Saxon Armoured Personnel Carrier as used by the British Army from the 1980s onward.
Exact dimensional accuracy is not guaranteed, particularly for the square cupola on top of the vehicle, but the principle dimensions should be good.
Wheels are printed separately; a spare wheel seems to have sometimes been carried beneath the left-hand side door.
I had good results printing at 0.15 or 0.2mm layer height in PLA on an Ender3.
EDIT: MontagueFlange pointed out to me that the military version has no door on the left side of the fighting compartment (the police version as used by the Royal Hong Kong Police had doors on both sides, however, as in my model). So I've made a version with the left door removed, which is uploaded here as the military version.
Thanks, Monty
