I have several different brands and models of 3D printers that print 24/7. I will 3D print ICUshieldMN face shields for free. These belts are great. They fit all the different printers I have and hold up great as has every belt I've used. In my photo you can see what a normal belt (left) and a stretched used belt (right) look like after 5 months of 24/7 use.
