This is a pack of various British and German deck guns that may assist those working on 3D prints for Cruel Seas, the 1/300th scale table top game.
Each gun is on a 2mm thick base. this requires a recess in the model's hull to mount it; they are not meant to be surface mounted. I suggest a recess of at least 1mm depth.
The large guns - the German 88 and the British S/A 6 pounder and 2 pounder QF all have 9" diameter bases, requiring a recess of 9.25mm
the smaller guns - the German single 20mm gun and the British single and twin 20mm all have 7mm diameter bases, requiring a recess of 7.25mm diameter.
I design these for filament printer; they need to be oversized at this scale to print successfully. I have received comments that the guns on my ships appear chunky, and this may deter their use if you have an SLA printer. I am dealing with small parts on a fine scale. I always error on the side of durability and ease of printing. My apologies to those looking for more detailed .stls.
I recommend printing at 0.06mm ("extra fine" in Cura) and use of supports is necessary.
