Crosley Radio Knob

thingiverse

This is a custom knob I designed in Fusion 360 to replace one missing from my dad's Crosley CR-9 Select-o-matic, an AM/FM/Cassette player that resembles mid-twentieth century tabletop jukeboxes found at Johnny Rockets and similar places. The photo shows the original knobs used for measurements, along with the printed knob. I've made a small modification since then to smooth out the edges of the knob and ridges slightly. The originals are chromed plastic, making it challenging to match them with a filament. Instead, we prioritized functionality. Print Settings: Printer: Maker Select v2 Rafts: Yes Supports: Yes Resolution: 0.1 Infill: 100 Notes: I printed the knob with 100% infill and 0.1 mm layer height using eSun orange PLA+. It's recommended to print it with the knob facing upwards for better surface quality. A support structure will be necessary for the overhang, and a raft or brim may also be required to hold the part in place.
