I just got my Sunlu S4 Filament Dryer and upon initial setup I realized those levers/handles provided do not allow for easy push to unlock and lift to open the dryer. I set out to create better handles that are longer to make pushing and lifting way easier. These handles slider over the existing handle and can be removed if wanted.

Along with this modification I also made better plugs which can be found here:
