Handle for Ultimaker Extruder-gear

thingiverse

Initially, I misunderstood the purpose of the hole in the extruder gear, assuming it was for a handle. Later, I discovered its true function but still thought adding a handle would be nice. To create one, I used my limited 3D-modeling skills and designed a handle for the Ultimaker Extruder-gear. Although it serves no practical purpose, it looks great! Printing required a high-resolution printer and a washer. My settings were 40mm/s speed, 0.1mm layer height, 0.35mm wall thickness with a 4mm nozzle, 20% fill density, and retraction enabled. A GCode file is also provided for lazy users. Printing went smoothly, but I had to remove some small pieces due to slow retraction. Assembly is easy; applying force is necessary to attach the handle. Ensure placing a second washer between the feeder and gear to avoid issues with the handle interfering. The handle stays in place firmly, though it might break if removed. This modification works for the original Ultimaker-gear and possibly replacements. I've included the Sketchup files, fixed STL file, and GCode used for printing. Please try it out, improve as needed, and feel free to comment!
