Easy to print M1918 155mm howitzer, 1/100 scale, will want some greebling if scaled up. Some details have been changed for looks/ printability. If you want the WW1/ interwar version, swap out the tire wheels for wagon wheels. For a towed version, cut off the handlebar bit and add a hitch hook.
Scale by 1.56 for gaslands / hotwheels / 1/64
