Arduino and Raspberry are great platforms that allows us to create both easy and complex project; there is literally a world of breakout boards that can be connected to these platforms allowing us to range over with creativity.
Breadboards and jump wires are great and helps to put our ideas working but have some limitations, especially when working on projects the should be tested outside the lab.
Therefore I decided to design a simple and 3D printable modular frame system capable to safely support veroboards, breakouts, displays, sensor, etc.

3D printable models are available on Thingiverse; please follow the link in the page.
