Description
For people with short/weak finger nails, that have trouble to the the ring lifted.
For people with little strength in their fingers or pain when pulling the ring.
Lift the ring with the pointy tip (works best from the side) and then use the lever to open the can with much less force.
Works even on the smallest cans. May be put on the fridge when you add magnets.
The opener prints fast with no supports when laid flat on the printbed while also resulting in the best structural strength.
Two versions available:
Basic opener
Opener with holes for 2 magnets 10x2
If you want to use other magnet sizes, just use the basic version and add negative cylinder in the slicer of your choice.
