My wife wanted a handle for her strainer.
I designed this in Fusion 360. The hardest part was figuring out the curve. I took a picture of the end facing me; converted it to SVG; scaled the SVG to match the real measurements; then tried circles and arcs until I got it close enough.
I printed it with a 0.6 nozzle (my first with this size). It was twice as fast as a 0.4 nozzle. It made a very tight fit.
