Micro Swiss direct drive extruder knob for Ender 3

thingiverse

Upgrading to the micro Swiss direct drive kit for the Ender 3? This extruder knob reclaims the original brass extruder gear as its core component. I grew weary of extruder knobs relying solely on plastic contact points, which can be easily rounded and compromised. To make this sturdy, the brass fitting requires a brief heating session before being pressed firmly into place within the knob. Simply hold it with a torch for a couple minutes to achieve the optimal temperature, then press it in. Once cooled down, securely attach using grub screws.
