3D Printer Extruder Handle (Ender 3, Ender 5) May work with other brands

Don't you hate trying to load filament but there is nothing to put your thumb on to get leverage? Your problems are over! This simple handle attaches to the extruder and provides a place for your thumb so you can easily get the leverage you've been looking for.

The "extruder handle V4" is for my Ender 3 Pro (first 2 pictures) and "extruder handle w cable bracket" is for my Ender 5. It has a bracket on the back to hold the cable sheath (pictures 3-5). I upgraded the extruders on both of my machines. I looked at the stock Ender extruder parts. Since it doesn't have the screw to hold on the spring that these upgraded ones do, this piece won't work with stock parts.

Attaching to the Extruder

Unscrew the screw that holds the spring in.
Attach the handle and replace the screw. The hole for the screw is recessed, so the original screw still fit.
