Nut Handle for 3D printer quick connect

thingiverse

To change filaments on a 3D printer, unscrew the quick connect without tools, remove the filament, and then secure the quick connect again. Reload the new filament afterwards. This method ensures an easy filament replacement process. As for this upload, it's my first attempt; let's see how it goes. I used Blender to create a 3D model with two cones. The first cone was scaled and the second one had six sides. I adjusted the X, Y, and Z dimensions accordingly. To remove the inner part of the first cone, I employed boolean/differential operation. Subsequently, I removed the second cone and recreated the thumb parts using similar methods. Finally, I exported the file as a .stl, suitable for use with Repetier when measured in mm. Note that Blender doesn't require metric or imperial dimension settings.
