x/y axis belt 608 bearing adaptor for 3drag/k8200

thingiverse

I'm creating an x/y axis bearing adapter for the 3Drag to boost its overall performance using some spare 608ZZ bearings I had on hand. I designed the original model with a 5mm inner circle, but upgraded it to fit the 8mm size of the 608 bearings for added stability. The new design features a small inlay that ensures the entire surface of the bearing is making contact. Additionally, I included a small hub to prevent belt slippage. Initially, the adapter was printed with a 4mm hole diameter, but this proved too narrow, and I've updated it to reflect its actual 5mm size. The modified model includes an adjusted mounting hole to ensure secure attachment. Coming soon is a software update that will add support for 4mm nut installation on one side, giving users more flexibility in their 3Drag configurations.
