  • This is so rad. Thank you so much for offering up this model. I can't wait to get it printed and include it in our event displays! 


  • @James Sanny Awesome! Don;t foget to post photos when you print it. :) 


  • I got my files printed and remembered I had one of those cheap pick LED modules. Turns out the board and battery tray fit nicely just inside the collar between the two halves. Adds a nice touch of ambiance to the whole thing - though I still hope to figure out some proper electronics for it at some point.

    Thanks again for the great files, Craig!


  • @James Sanny That looks great! I really like the color combo too!
