Cairo Mini 3d-Printer: Building The Structure

Difficulty:	Easy
Steps:	3
Time Required:	30mins – 1hr

Step 1 _{^{Connecting Base and Y profiles}}

Prepare The Following Parts:
2040 Y-axis Aluminium extrusion(400mm)	1
2040 base Aluminium extrusion(340mm)	1
M5 T-nuts	2
M5x40mm Hex screws	2

Insert the two M5 T-nuts into the Y-axis aluminum profile.

Place the Y-axis Aluminium profile on top of the base Aluminium profile maintaining the shown distance.

This is an important step as other steps will rely on the accuracy of this assembly.

Then insert two 40mm hex screws and gently screw them.

Then insert two 40mm hex screws and gently screw them.

As you have noticed, there are two 5mm drills in the base Aluminium profile. We used these two drills to connect the base Aluminium profile with the Y-axis Aluminium profile.

Step 2 _{^{Assembling The Z-axis Extrusion}}

Prepare The Following Parts:
2040 Z-axis Aluminium extrusion(400mm)	1
M5x60mm Hex screws	2

Place the Z-axis Aluminium profile vertically on the base Aluminium profile.

In the base Aluminium profile, there are two M5 threaded drills. Gently screw the two M5x60mm screws into it.

As you have noticed, there are two 5mm drills in the base Aluminium profile. We used these two drills to connect the base Aluminium profile with the Z-axis Aluminium profile.

You now assembled the main Aluminium profile structure.

Step 3 _{^{Assembling The Z-axis Stepper Motor}}

Prepare The Following Parts:
NEMA 17 Stepper Motor	1
M5x12mm Hex screws	2
M5 T-nuts	2
M3x20mm Phillips screws	2

Insert Two M5 T-nuts into the Z-axis Aluminium profile from the top face of the profile.

Install the Z-axis stepper motor holder on the bottom end of the Z-axis Aluminium profile using two M5x12mm screws. Make sure that the stepper motor holder holes are aligned with the two M5 T-nuts.
