Volvo Brake Piston Tool C30, S40, V50, C70 etc

This is a handy tool designed to retract brake caliper pistons on Volvo and Ford vehicles. To use it effectively, attach a 30mm socket and apply gentle yet firm pressure - approximately 20 kilograms or 200 Newtons should suffice. As you turn the socket clockwise, the caliper will begin to retract smoothly. The tool requires two M3 hex head bolts for securing the pins, which are roughly 20 millimeters in length. Simply screw them into place, but leave about a few millimeters of excess material at the end for an optimal fit. I printed this tool using PLA with a 30% infill density. This design was inspired by Thing #216291, a similar project that sparked my creativity.
