easy carts upgrade with nuts

thingiverse

I remade these cart upgrades using designs from SgaboLab, adding spaces for nuts to make it easier to achieve the right tension on pulleys and wheels separately. I also added some height to account for the washer needed to align the pulleys with my machine, which required approximately 1.4mm of extra space. To use the pulleys effectively, you'll need longer M5 bolts for each carriage corner. I used 50mm bolts, which fit snugly, so finding 60mm bolts would provide more room to work. SgaboLab's original design can be found on Thingiverse: https://www.thingiverse.com/thing:2574935. I sourced my pulleys from Amazon, one of these models: https://www.amazon.com/gp/product/B01H3F8LUU/ref=oh_aui_detailpage_o05_s03?ie=UTF8&psc=1, and two of these models: https://www.amazon.com/gp/product/B01H3DNKYY/ref=oh_aui_detailpage_o05_s03?ie=UTF8&psc=1. I utilized bearing spacers from a wheel kit I had for an older machine. Aliexpress might be a good source to find those spacers.
