Upgrade spring compatible Ender 3 handle

This is an updated version to fit with the upgraded Ender 3 springs since people were saying the original version of the handle is too thick to work with the upgrade springs.

I just measured the diameter of the new springs and recessed 2mm out of the 4mm thick handle to accommodate the springs. Fits perfectly on my Ender 3 V2.

Make sure to build this with support.
