3D model description

Link to instructables: (Please, vote for me :)

Doter is a huge dot matrix printer based on Arduino. Most of the parts are 3D printed, there are also 28BYJ48 stepper motors (the cheapest stepper motors you can find) and some basic components, there is also PCB that you can buy right here. It can print on the paper up to 55cm wide and infinity long. More info about this project can be found on instructables.

None of this models need supports, pulleys has supports build in, because it would be impossible to remove supports from the inside of the pulley. Those models are rather easy to print, but it takes some time, because they are quite big.

Wheels that will move the paper should be printed with flex filament to do it better. I made a rim for this wheel that should be printed with PLA and on this wheel you can put a rubber wheel.

You can also buy PCB for this project on tindie:

For more info don't forget to check out instructables project about doter. That's my biggest project when it comes to size, and that's awesome! If you have any idea of what I can print on 30 meters (yes, meters) long paper, let me know in the comments!

In general, I think I can call my self a maker. Filmmaking, CNC, 3D printing, Design, electronics, robotics, sports that's what I am into.
