A1 ajustable feet

My printer being placed on an uneven surface, I therefore decided to make feet with adjustable height, they also reduce noise and vibrations.This assembly is made up of 6 pieces (2 separate pieces per foot). My first idea was to use TPU for all parts but I saw that threads in TPU are not printing well so I chose to use PETG (or PLA) for the lower part and TPU for the upper part with support enabled.
