Step 25: Print area support assembly
| qty | part name | description/notes |
| 2 | LM10LUU | 10mm linear bearing with housing |
| 1 | LM10LUU screw kit | 8x M5x20 screw, 8x M5 washer |
| 1 | Print area support L-shaped | File:Print area support-L-shaped plate.PDF |
| 1 | Z endstop holder | |
| 1 | Trapezoidal nut | with 4x M4x20 screw |
Fasten LM10LUU linear bearings and the L-shaped plate with M5 screws (Linear bearings must be placed on the internal side of L-shape) and, on the other side, the trapezoidal nut through M4 screws in this manner:
Step 26: Z axes and trapezoidal thread
| qty | part name | description/notes |
| 1 | Trapezoidal screw 12x3, length: 380mm | 12mm length machined to 10mm diameter |
| 2 | Z shaft 10mm length 390mm | 10mm |
Screw the trapezoidal thread in the nut and to the L-shaped plate.
Insert the two shafts in the LM10LUU bearings
Step 27: Z stepper motor assembly
| qty | part name | description/notes |
| 1 | Z Stepper motor | nema 17 1.7A |
| 1 | Z Stepper motor screw kit | 4x M3x20 screws, 4x M3 washer |
| 1 | Motor-Trapezoidal screw coupler | flexible coupling 5 mm and 8 mm diameter |
Take the stepper motor for the z-axis and join the motor shaft toward top to stepper plate with the screws and washers (stepper motor kit of this section checklist).
On the other side of the stepper plate, add the flexible coupling to the motor shaft (5mm of diameter).
Step 28: Assembly of z-axes on structure
| qty | part name | description/notes |
| 4 | SK10 Shaft support | 10mm shaft |
| 10 | T-nut (Bosch 3842523925) | used for stepper plate and SK10 |
| 10 | T-Bolts (Bosch 3842523920) | used for stepper plate and SK10 |
Widen the holes of shaft supports to 6mm of diameter, to allow the connection with the profiles trough M6 T-head bolts.
Join the shaft supports to the mid-rear and upper z profiles with T-head bolts. Insert the z-axes in shaft support holes.
Now, join the free side of 8mm diameter of the coupling with the cylindrical part of the trapezoidal thread.
Step 29:Print plate (Heatbed)
| qty | part name | description/notes |
| 1 | Aluminium heatbed support | File:Aluminium heatbed support.pdf |
| 5 | M5x20 - washer - nut |
Step 30: Z Endstop holder
| qty | part name | description/notes |
| 1 | Z endstop tuning support | File:Z Endstop tuning.pdf |
| 1 | Z endstop knob | use a grub screw to fix M4 threaded rod |
| 1 | Z endstop spring | |
| 1 | Collar nut (Bosch 3842523925) | used for Z endstop holder |
| 1 | T-Bolts (Bosch 3842523920) | used for Z endstop holder |
| 1 | M4 threaded rod length 60mm |
