I visited a friend's apartment and the faucet handles to his sink were missing. I couldn't leave that alone. I snuck a caliper into his bathroom on his birthday for measurements and made these for him the next week. 1: Print it. (*optional: Spray the skulls chrome and paint the eyes red/blue) 2: Attach the splined shaft to the faucet. 3: Pop the skull onto the splined shaft. 4: Glue on the eyes. Notes: If you do not have a keyed shaft (aka D-shaft, like on stepper motors) like he did, you'll have to make your own splined shaft adapter. (Edit 'faucet.scad') The "spline.scad" file is a library or sorts. It'll get imported to make the splines (the things that look like rocket fins) that interface the skull to the faucet shafts.
