Back, last Christmas, when I first got hold of a resin (SLA) 3d printer I decided that I was going to attempt to do a WWI 1914 in 6mm for the Joy Of Six show. I decided to use the excellent range by Henry Turner which had everything I would need.
Unfortunately other things distracted me from this project and it didn't get too far. It didn't help that I'd decided to use water-washable resin for the minis and this was very brittle and the models broke very easily.
Roll on to August, and I could get back to the project. I started again with some Sunlu High Toughness Resin, which is really flexible and takes paint well without a primer. This has worked really well and my 1914 BEF force is now ready.
I initially looked at Great War Spearhead II as the rules to use, but these seem overcomplicated for what I need so I've been looking at other systems. Peter Pig's Square Bashing was suggested to me and that looks to be good for fun pick-up games at the club, but really I want to run a scenario game based on the whole or some part of the retreat from Mons. The "Bloody Big Battles" rules set looks promising with the modifications available as a free download and there is a complete retreat from Mons scenario.
So I've tried to be relative rules agnostic and have based my units on 30mm squares (3d printed) with enough to make a Square Bashing army or the army for the BBB Mons scenario.
I'm now on to my Germans... there's loads to do!
