Machine rotary knob

thingiverse

A rotary knob designed for industrial use in bakeries, kitchens, and similar settings was created to replace a damaged Bakelite knob on a dough-kneading machine. The black ABS version looks appealing with 0.1mm layer thickness. The OpenSCAD file of the original design is included for customization purposes. Users can modify, tweak, or hack the model to fit their unique machines. The printing process involved using Ultimaker and Netfabb software, although Cura is recommended due to its better pricing. Recommended print settings include 0.1mm layer thickness and moderate printing speed (~50 mm/s) for a polished outcome. The nozzle temperature should be 240°C, while the bed temperature should be at least 95°C. However, be cautious that the shaft is designed oversized to account for shrinkage during cooling, which results in a narrower hole. To achieve the perfect fit, calibrate your printer by printing only the knob's shaft part, measuring the shrinkage, and adjusting the shaft size accordingly in the scad file.
