Key for the carpet holder foil holder

KEY for RobinP's great tarp clip
Delicate or wet hands, painted fingernails?
No problem! My girls could no longer loosen the flat screws when I tightened them.
That's why I designed this key.
It can be printed upright and then break the support structure at the bottom with a screwdriver.
Printing the key once is sufficient.
Printed in PETG with 0.2mm layer, 5 walls & 20% Gyroid Infill.
