thingiverse

<h3>This is set of knobs for a 1938 Elektrit Allegro radio.</h3> <p>Included are:</p> <ol> <li><b>Allegro center big</b>, this is main tuning knob, outer diameter is 70 mm, mounting shaft has diameter of 9 mm. <li><b>Allegro center small</b>, knob for changing band, outer diameter is 30 mm and shaft is approximately 7 mm. <li><b>Side right and left</b>, are knobs for volume and tone, the right knob is for tone and it has small circular hole to indicate its position. Both knobs have diameter of 38 mm and 6 mm shaft. Painting the circular hole in tone knob with white marker is recommended. <li><b>Allegro center small</b>, knob for changing band, outer diameter is 30 mm and shaft is approximately 7 mm. <li><b>Side knobs inner ring</b>, this ring replaces the brass ring that is on the inside of the side knobs. I suggest smoothing it with sand paper and painting it with gold (use "antique" gold) spray paint before gluing it. </ol> <h3>Printing the knobs</h3> I have printed all knobs with 0.12 mm layer height (0.4 mm nozzle) and 55 mm/s speed in PLA and they looked very nice. <br> Underneath each knob there is a slot for a nut that is used to hold the screw that will push against the shaft . I suggest using M3 nuts, you can file sides a little bit to fit them into a rectangular slot.<br> <h3>Other knobs </h3> <p>Check out my profile for other knobs if you are interested in restoring vintage radios.
