Have had a couple people say that at 1/12 it breaks at the holster connection to the harness. I'm making a quick fix for 1/12 scale so that area is thicker. I'll post it today and if you have purchased this already please download the update.
Yes it will require supports. I suggest Elegoo Resin (pick the color you want as your base color), then add 30% SIraya Tenacious flex resin. I prefer to separate the belt and print it separate from the harness. The files are separated so you can do this.
I will add, this thing has great details that can be seen in 1/6th scale. It is configured to also print in 1/12th, but you do not see the details in the harness. (threading, leather grain etc.)
Does it need supports added and what’s the best resin to use?
