Have you ever thought of using the 80/20 T-slots for the structure of a 3D printer? Maybe you never think about it, but in fact, it is the best option here.

For this project, you will use the 80/20 T-slot, where it can be purchased from the 80/20 Garage Sale on eBay. The Fabr frame is a 1″ profile ‘1010′, 12 totals with each 14″ in length. You need to use 8 three-way nylon connector to complete the cube and a few bearings to act as the glider over the slot.

Although the 80/20 T-slot is very good in quality, but there is still a side effect using it as the main structure of a 3D printer. The weight is greatly more than the reprap design using rods and plastic joints. You must know that the 600ma Stepper motor cannot drive too much weight or even overcome the friction of the linear motion bearing.

Therefore, you have to design the “super driver”, where it capable to drive up to a 2.5 amp Stepper. [read]
