Tool to install BSA30 ZTTO bottom bracket bearings. Search "BSA30" on aliexpress. I upgraded my half inch drive after initially printing it with a pipe wrench, which turned out to be a smart move. It requires a decent amount of torque and helps avoid damaging the aluminum shell. Use 4+ edge layers and 25-50% infill.
