WELL... After looking into the handheld water-sprayguns from Karcher, a coherent brand identity wasn’t found. A deeper look into the the ‘main’ products had to be done. Time to look into the high pressure cleaners.

FROM 2D TO 3D After sketching, several prototypes have been made to continiously get feedback about proportions, size, feeling and aesthetics.

nr. one This model has been made by hand directly after sketching.

nr. two An improvement of number one where volume has been added.

nr. three A milled prototype to check size and test with users.

nr. four A final 3D printed prototype that works!


FROM 2D TO 3D Sketching, sketchmodelling, surface modelling, sanding, 3D printing, soldering, breaking parts, glueing parts, painting and presenting!


CHANGING ELECTRONICS The switch that was soldered on the PCB was removed (and broken unfortunately). Cables were soldered on the PCB to put the switch on an other place on the screwdriver.




LOST YOUR BITS? The integrated bit storage has space for three extra bits. The storage can be accessed by sliding the compartment backwards.

COMPONENTS The components of an existing 15 dollar electric screwdriver have been used as a reference and the product is built around these components.

EXPLODED VIEW The product can be produced by injection moulding two shells. Overmoulding the handle will give it a rubber texture. In total two screws are visible, while three screws are being used. One of these screws is hidden behind the bit storage.
