Don't Panic sign! Thanks to Muzz64 for creating the Don't Panic version, that I requested.
Here it is all printed, and for the lettering I just used a sharpie to colour it black, and looks pretty good, I think.
During the print I was worried that the pull-out support was going to be completely stuck! While it's not printed the support the total best, it's not a very visible component. Overall I am extremely happy. with the sign!

I found adhesion a challenge on the rear support, and for some reason it warped on my first 2 proper attempts to print. I rotated the model and sliced again, and the issue went away.
My final print had it rotated 45 degrees, and my sliced uses a cross hatching layer-by-layer, and so this meant that my mayers were in-line with the angle of the model, and actually this worked really well, and it has a great look on the finished sign, as my top-layer happened to go 'up and down' the sign.
