Heathkit Paddle Knob - uses existing collar
thingiverse
This paddle knob is very similar to Plastman's https://www.thingiverse.com/thing:1412639 Heathkit SB-102 Paddle Knobs. Unlike the parent part, this one is designed to make use of the existing metal collar, allowing you to completely control the alignment between this paddle knob & the shaft. I redesigned this from the ground up in ViaCAD 2D/3D, taking measurements from an original Heathkit paddle knob (minus the paddle, which had broken off). For your convenience, I've posted the required STL print file, the original VCD design file, as well optional design files in a couple of other 3D formats (IGS, 3DS, STP) as exported from ViaCAD.
