This is the first army I've done with a significant number of 3D printed models, and I feel like I ought to thank all of the designers whose work I've used here, particularly Miffles_makes, JanZizka, Woddish, Mkhand_Industries and Tdoesepic. All the printed models in this army were made using free files, and I am really grateful to all the designers who are producing this material for the community.
Next up I'm hoping to do a few more Chaos Titans to go with the Ravager. After that I'm planning on revisiting my Eldar. As well as more '6mm truescale' titans, I have a variety of additional units I'd like to add and a few that I'd like to re-do. I also have Tyranid and Tau armies waiting in the queue. And one day I'll finally get around to those Orks.
