Strong Pulley for M3 metric bolts w/ bearing

thingiverse

I was initially drawn to the pulley design for econopotamus but decided to use the bearing I had on hand instead. The side blocks and hanger blocks remain identical, yet the wheel is now comprised of two separate components that fit snugly within a standard bearing. As the outer part nears completion in the printing process, inserting the bearing into the still-warm component proves instrumental in achieving a perfect fit. Once the part has cooled down slightly, it will contract and securely hold onto the bearing.
