Cup wrench and insert tools designed to fit a BBR60 bottom bracket. The insert was designed to fit a Parktools BBT-9.

Can't really speak to longevity when using these tools, but please (please!) wear eye protection and appropriate safety gear when in use. I was able to get quite a bit of force applied using the 1/2" square drive on the cup tool model printed with Anycubic ABS-Like Resin Pro 2.
