Small key to reset Fire alarm or panic alarm etc, whatever uses FP2 key.

Just be aware key only needs to turn about 5 degrees or so until resistance is felt, don't try to turn fully as this is unnecessary and may snap the key.

Print as supplied, use support (it wont take much and key prints in about 6 minutes)

Cura support angle 40 degrees gave good support and peeled of easily.

0.2mm layer height.
