TinyCart v3 - UBR

This is version 3 of the printer that i designed, which utilizes very cheap and available 2020 profiles and perforated steel plates it is by far the most low cost solution for small 3d printer i have encountered. It is suitable for someone who wants to create their first REPRAP due to ease of building. It requires printed part though.

I believe the model is easily scalable (as smooth rods, 2020 extrusions and perforated plates are needed), but my current setup have bed 155mm (X), 160mm (Y) and 200mm Z axis height.
This utilizes :
-2x 2020 320mm
-2x 2020 350mm
-3x 80x240mm perforated plates
-2x 8mm 355mm smooth rods
-2x 8mm 345mm smooth rods
-2x 8mm 280mm smooth rods
