The handle in the form of a spool with a thread is installed in place of the original handle and fastened with the same bolts!

There are spools with inscriptions PLA, PETG, ABS, TPU and a spool without inscriptions with my design, through which you can see the color of the thread on the spool (what color the thread on the spool will be depends on you)

there are models for the main filament spool for those who do not want to change the color of the filament in the future and a spool with a replaceable filament

Installation:

Unscrew the original door handle and replace it with the same bolts to screw the handle (spool) on, then screw the spool with the chosen design into it!

(If you are interested in this model, I will add other designs later)
