Printing: I printed the gears/letters upright, so there is support material to remove. Be careful when removing support, as the section connecting the gear to the letter can be delicate. I stiffened up the “A” and the “G” with a support rib in the back because I had issues with the connecting section breaking during support removal. So be especially careful with those letters! Post-Printing: Carefully remove support material as discussed above. The video (and exploded view) show how to assemble this. Be sure to get the positioning of the gears/letters correct, with respect to each other, so they are synchronized when turning. I find it helps to press each gear/letter on in order, from “A” to “S”, with the logo facing front (revealed). You can put a little super glue or epoxy on the top of the “Mounting Shaft, Avengers Logo” shafts before pressing the gears/letters in place, if you want to ensure the gears/letters can’t pop off. The base is printed in 3 parts for those with small build envelops and just needs to be pressed together.
