Building the EdPrinter
It’s time to build a printer out of LEGO bricks!
The EdPrinter is an advanced project and requires a high level of building skills. As the EdPrinter uses some generic parts (rubber bands and pen) some fine-tuning is also required.
Clutch drive gear
Paper feeder support
To fit the felt tip pen or marker, slide it under the two rubber bands. Some adjustment will be needed to get the pressure on the paper just right.
Cut a piece of A4 paper in half (A5 – 8.27in x 5.83in) and then while lifting the paper feeder Edison slide the paper into position.
Position the pen close to the pen controller Edison. Press the play button on the paper feeder Edison first and then press play on the pen controller Edison. Your EdPrinter will now print a square.
