Synfosy wanted a design for its Arduino microcontroller kit casing. The prime design objectives were: safety, durability, high accessibility, and “an awesome look”. Our job was to create an attractive design for the case.


Putting the components together was quite challenging for the team. We discussed each element of the product requirements along with the end-user expectations and experience. We helped to define the requirements of the product and accessibility among the user community. Based on this, we further developed the design build.

Our team developed multiple sketches, giving the client several options from which to choose according to their expectations. Once a design selection was made by the client, we addressed the engineering design challenge. The casing had to accommodate a variety of external connectors, including 15V power supply, electronic cable, and USB. The USB needed to be accessible when opening the casing (via screws, to comply with the relevant safety regulations). As well as allowing for 1 sensor M12 4 pin female plug, we created a design that could accommodate a second M12 4 pin female plug alongside the first sensor plug, if required. We recommended an injection molding production process using ABS.


An average Arduino microcontroller costs $40/each. It was certainly a challenge for us to keep the production cost below $10. But, with that all covered, we progressed to 3D modelling and designed for manufacturability. We rendered photorealistic images to share with the client. Finally, we were able to create a highly functioning engineering design with a low production cost. Sinfosy were happy with the bright-colored design and the product stackability – which ensured the finished result was in line with their expectations.
