Magic potion

After everything is printed, the parts for the holder are only screwed together, not glued. The bottle sits loosely in the holder. If you place the parts to be molded in hot water or on the hot print bed for a while, or carefully heat them with a hairdryer, they can be easily shaped without breaking. This was not necessary with my model, but this can vary from filament to filament, even if everything is made of PLA.
