Introducing Flippy! The all-in-one modular 3D printed electromechanical seven-segment display. Through the use of 14 electromagnets, each digit is able to quickly and mechanically display both numbers and letters. This creates a unique and satisfying display.

 

To build your own, check the full build instructions on Instructables: https://www.instructables.com/3D-Printed-Electromechanical-7-Segment-Display/ 

Print all parts in PLA apart from the PCB clips which should be ideally in PETG. Print all parts in your “primary” colour (in my case black), and then the “white” parts in your “secondary” colour. 

Almost all of the parts can be printed without support, apart from the IR disk and electronics box housing & lid.

If you use Orca (or Bamboo) slicer, I would highly recommend using the provided .3mf files

SPOOLER ONLY: If you are building a spooler, you will need a servo mounting bracket. The ones I used can be found at the link below. I cannot share the files directly due to the licence type. https://makerworld.com/en/models/423292
