Food Can ring-pull opener

A simple ring pull can opener (for large food cans). Two versions Mk1 is a T-Bar for people who can still bend fingers around & grip a 25mm T-Bar handle. Mk2 has a pommel for people who can't bend fingers as far, but can still wrap around a larger object (the Mk2 also has a larger radius on the hook making the effort to open slightly less).

The opener is slipped into the ring pull (hook end up) and then rolls back, on its own outer circumference to open.

Suitable for anyone with a weak grip or forearm strength restrictions such as MS sufferers (one in particular for whom they were made); but equally for anyone with those restrictions, irrespective of cause.

Print in PETG with 40% gyroid infill and 5 perimeters for strength. PETG is both food safe and waterproof/washable. Prints require a little bed contact support and an enforced support for the end of the hook (both built in to the gcode / bgcode files - MK3 & Mk4 printers). Both also provided as an stl.
