Thanks to the designer for a great design. I wanted something different for the front of my traction engine. That can be fond here : http://www.thingiverse.com/thi...  so come up with this. I found the face at http://www.thingiverse.com/thing:293591 : but i don't own it (I hope the designer doesn't mind me using it like this). PLEASE NOTE: I have not printed yet so can't guarantee this is 100% correct. I will post pictures once I've printed. There are 2 different designs there. Smoke_Box_Front_REDO_Face = Is just the face only on the existing piece. Smoke_Box_Front_REDO_Face_Arm = Is the face on the existing piece + a hole for the arm. 2/3/17 - I have just uploaded the 2 x halves so you can print in 2 colours. I have also included a photo of the actual item.
