Franke Perlator/Aerator Key 4-prongs ~25mm

I was unable to find such a key for franke pescara slide-in perlator. 

Printed in standard PLA. Add a raft for good measure because a footprint is rather tiny and likes to detach 

with 0.6mm nozzle and 2 perimiters you'll get a nice, tight fit

with 0.4mm nozzle you should probably aim for 3 perimiters, but I've not tested it.
