Multimaterial Firetruck

Facts first: This is a remix of a print-in-place firetruck, which adds separate components for up to five colors/materials. Now for the story...

My son wanted me to print a fire truck with my new Palette 2, but the two-color version I found wasn't printing well (the headlights and bumper weren't inset into the main body, preventing them from attaching well). So, I remixed the original design in Meshmixer to make it easier to print, and while I was at it I split the components out for more materials (so you can go wild with your MMU2).

The versions in the picture are both only three materials (copying the original). One is at 100% size with .32 layer height and the other is at 40% size with .2 layer height. The larger print had some issues entirely independent of the model. Sorry I didn't opt to reprint in higher print quality, but I was in a hurry.

Print instructions

The bridges in the model require adequate cooling, but other than that the tolerances can be pretty loose. You may need a brim for the ladders, but everything else sticks quite well without extra bed adhesion (and is a pain to clean up if the brim sticks too well or there's excessive elephant foot).
