1/4 Inch Potentiometer Knob

thingiverse

Slim knobs made from plastic. This was created to imitate missing knobs from an oscilloscope made by LeCroy. It fits well on a shaft with a D-shaped end that's 1/4 inch wide. Several slight variations have been made: Single piece, Two-part base and cap (with two-color print) and Two-part core and ring (also two-color print). The idea behind the two-color prints is that they can be colored to identify them. All were printed on a Makerbot Replicator 2X using ABS material, with some in natural color and some in antistatic color filament. Dimensional checks show it fits properly but prints come out a bit messy when trying to print multiple colors at once on this machine. Antistatic filament needed lower heat settings for bed temperature because it came out too pliable at standard temperatures, so I used 10 seconds in the microwave to soften and stretch over the shaft. **How to Use:** A two-color print can come out pretty messy, so if you need multiple colors printed on the same knob, you should just stick with a single color or change filament mid-print instead. If possible, use the default settings for this printer and set layer height lower because it's a small object. Use at least 2 shells for better results and recommend fill level be about 25% high to maintain stability.
