Backpack Mini Delta 3D Printer

## What is the backpack?

The backpack is a low budget 3D delta printer. He uses the favorable 28BYJ-48 step motors and fits in a backpack as well. The idea for the backpack arose when there was a gap between the [Low Budget 3D printer](https://www.derpade.de/mein-selbst-gebauter-3d-drucker-aus-altem-pc-material/) and The [Sparkcube v1.1](https://www.derpade.de/bauanleitung-sparkcube-v1-1-bautagebuch/). The 28BYJ-48 stepper motors fill the gap between stepping motors from CD drives and Nema17 motors. From this gap, the following requirements were formed.


_In this project several hundred hours have passed. From the idea, to the design to the prototype, it took a lot of sweat and effort, not to forget the investment in several components and several prototypes. For this reason, I would like to draw attention to the possibility in the form of a PayPal donation._
