I have a Prusa i3 MK2S printer which I love (and hate, of course, but mostly love) and I use Fusion 360 to design my 3d models. I almost never print with PLA because I’m paranoid about my prints drooping if they get left in an overheated car in the summertime. I’ve used loads of different filaments but one of my favourites is ColorFabb HT. I’ve made enclosures for my electronics projects, mechanical parts, and some decorative pieces. My animatronic ostrich head is completely 3d printed including the beak and the eyelid mechanism and mounts for the servos.
