you wont print it on a pulse though. This one needs a 300x300 bed or larger as the big ring holder are 286mm end to end. I used HIPS cause I pick it up for less than $10/kg and so its less of a problem if you have to reprint something cause it doesnt fit then if you use Nylon
Now this is one you might be able to print on a pulse
The Holder is ABS the gears and Rim Nylon 910 and the tire TPU.
All was printed on a Chiron
