J-38 Knob 16.5 mm Radius
thingiverse
I've had my J-38 Key break off its knob after nearly three decades of faithful service. A replacement knob that fits perfectly is exactly what I needed, and this one does just that. Measuring 33mm in diameter, it's ergonomically designed to fit comfortably in my hand. The design can be easily scaled up or down to meet individual needs. The screw hole is relatively small, but it could be enlarged to accommodate various screw sizes if necessary. This part was created using FreeCAD and printed with nylon by Jawstec.com.
