About this 3D model
The original liquid detergent guide provided with the washing machine didn't work as it should: it doesn't hold the liquid in the tray and I wasn't able to use the prewash program. So I designed a remake to make it work properly. My washing machine is Samsung WW90TA046T but it should work with every Samsung WW9, WW8 and WW7* model. I printed upside down with support material (see picture) on a 0.4mm nozzle with 0.5mm Line Width at 0.16mm Layer Height.
