Here's a couple of prints of my 1:100 (15mm) AEC Deacon model.
The Deacon was a 6 pounder anti-tank gun mounted on an armoured AEC truck chassis. It was used as a SPAT solely in North Africa in 1942-43, but some were later converted for use as unarmed armoured ammunition carriers for use in Italy and Normandy.

The one on the left was printed at 0.1mm in eSun PLA+, the one on the right at 0.08mm in PLA. The PLA+ printed much cleaner, though both suffer from a lot of noise in the Z-axis — apparently I need to do something about separating the lead screw from the Z-axis motor. More research is indicated.
