Simple Knob Cap Ender 3

thingiverse

I designed my own knobs for my Ender 3 since I couldn't find any that were a good fit. They either came out too small or too large, which made them useless. So, I decided to take matters into my own hands and create something custom. My design is straightforward, prints quickly, and it's actually really fun to use. One of the best features is how fast you can adjust the temperature from 0 to 200 degrees Celsius - it's a huge time-saver. The button on my knob has a diameter of 25.55mm, which may make it compatible with Creality buttons that have a similar size, or at least those that are around this diameter. To ensure a snug fit, I intentionally set the diameter to 25.50mm - if you find that it doesn't fit perfectly, just scale it up by about 1-2% and you should be good to go.
