Heathkit Paddle Knob - uses existing collar
thingiverse
This paddle knob closely resembles Plastman's Heathkit SB-102 Paddle Knobs on Thingiverse. It differs from the parent part by utilizing the existing metal collar, allowing for complete control over alignment between this paddle knob and the shaft. I completely reworked this design in ViaCAD 2D/3D, measuring an original Heathkit paddle knob without the broken-off paddle. To make things easier, I've posted the required STL print file, along with the original VCD design file and optional files in other formats like IGS, 3DS, and STP as exported from ViaCAD.
