Hi Allan,
Wow small world I just randomly came across your post, and I'm doing exactly the same thing as you, at the same time, I'm currently printing the Eclipson Model C using my new Creality Ender-3 S1 Pro, it has the CR touch and its the most awesome thing ever, my old printer had to be levelled 100% manually so I wanted a touch levelling system this time.
The magnetic build plate is very good too, every print sticks well.
Anyway I'm not going to bother painting the first model cos magnetic trees etc, etc.
We can compare notes at the field on Sunday if you like, I think this will take me a few weeks to build, even without finishing the paintwork.
I'm also thinking of getting a vinyl cutter so any advice you can offer on that at the field would be great as I know you have one of those, or perhaps if I supply the material you could cut the decals for me. :-)
