Recessed (Cache) Aerator Keys (Multiple Sizes)

thingiverse

UPDATE (06/04/19): At SuperSonicFlea's suggestion, I added wings to the bottom of the models to simplify gripping and turning. The alternate STL and STEP files have 'Wing' appended to the end. After sweating in a new branch of copper piping, a significant amount of sediment was flushed further down my water lines, plugging a bathroom faucet with a recessed aerator installed. To resolve this issue, I bought a multi-tool on Amazon for approximately $9 (considering printing one up, but it seemed like a trial-and-error design process, especially due to mineral buildup and the lack of available designs on Thingiverse). Realizing that I'm not alone in needing this solution, I decided to create various sizes that my purchased multi-tool had (only able to test the M18.5 size). The four available sizes are: M24 - Regular M21.5 - Junior M18.5 - Tiny Junior M16.5 - Tom Thumb After printing a test piece, I decided to lengthen each model for better gripping and add labels for easy identification. I've included the original Fusion 360 file as well as a STEP file in addition to the STLs for modification if desired. If you print these models, please post a make so I can see how yours turns out! Any feedback is also greatly appreciated.
