## Designing of the Frame

* Aluminium channel of 40x40 mm is opted for the construction of the frame of the machine.

* The Aluminium channel is further cut into 12 pieces for the cube assembly.

* 8 pieces of length 400 mm each for the X & Y axis.

* 4 pieces of length 500 mm each for the Z axis.

* The channels are held rigidly with the help of angle brackets as shown below.

## Motor Mounting

* Attach the motor for the X motor mount printed part as shown below.

* Mount the GT2 6mm 20 teeth pully to the motor and fix the entire assembly in the top corner of the Cube.

* Attach another set of motor to the Y motor mount printed part as shown below.

* Mount this motor assembly to the bottom side of the cube.

* The motor assembly must be fixed as shown below.

## Z axis Mountings

* Attach the Z Shaft clamp printed part at equal distances and ensure that they are alligned properly on both edges of the bottom end.

* Also attach the Z Shaft clamp printed part to the top end.

## Z axis Smooth Rod

* Place the smooth rod through the Z carriage printed part as shown below.

* Now attach the smooth rod assembly to Z shaft clamp.

* Repeat the same procedure on all 4 sides as shown below.

## Print Bed Frame

* The print bed frame should be firmly fixed to the smooth rod assembly.

## Z axis Screw Rod

* Attach the 6mm to 8mm Coupler to the Z axis motor.

* The screw rod assembly is fixed to the Z axis motor.

## X-Y axis Smooth Rod

* Place the XY idler printed part on the top side edges of the cube.

* Insert the smooth rod into this assembly.

* Place the XY joiner around the smooth rod.

## Print Head Assembly

* Attach one of the end stop switches to the X Carriage printed part.

* Place two smooth rod assembly.

* Place this assembly as shown below.

* Attach the cooling fan with E3D hotend.

## Pulley Belt Installation

* Pass the belt along the edges of the printer through the printed parts as shown below.

## Filament Extruder

* The extruder motor is attached to one of the edges of the cube.

## Electronics

* Ramps 1.4 board with A4988 motor drivers.

* Mount the Ramps board on top of Arduino Mega as shown below.

* SMPS unit of 12V & 21A

* RepRapDiscount Full Graphic Smart Controller.

* Heat bed.

* Place the end switches.
