making Base Frame

First I designed Base frame of my own 3d printer.
CAD is Fusion360.
Materials as following...
SF-20・40 SF9-242 500mm
D Bracket SS w/screw-tap SFJ-017
ST Nut SS(M5) SFN-TX5
Adjuster M8×21ｍｍ clear
Claw nut M8
MDF 6mm

attach Y_axis_Stepper motor_assy & Timing Belt_Block_assy

Then I attached Y_axis_Stepper motor_assy & Timing Belt_Block_assy to the Base Frame.

Materials as following... 

Stepper Motor NEMA17   
Motor Bracket QP01  
GT2 Timing Pully   
Liner shaft clamp x 2
 Bearing  8 x 22 x 7 mm
Liner Shaft φ8mm

attach Modeling_table_assembly

Next, I attached Modeling_table_assembly to the Base.

Materials as following...

liner shaft support SHF8
liner shaft φ8mm
liner motion ball bearing slide unit JPF-3D-XSZC-4PCS
acrylic raising block
aluminum plate

attach Z_axis_motor and lead screws

Next, I attached Z_axis_motor and lead screws to the Base.

Materials as following...

NEMA17 stepper motor
Helical beam coupler φ5mm-8mm
lead screw T8-2-D8 φ8  400mm
liner shaft support SHF8
liner shaft φ8mm
liner rail shaft clamp SK8

assemble X_axis_Stepper motor_assy and hotend_unit

I assembled X_axis Stepper motor_assy and hotend_unit.
Materials as following....

NEMA17
GT2 Timing Pully&Belt
Timing Belt holder unit
Bearing  8x22x7mm
Bearing holder block module
liner shaftφ8mm
liner rail shaft clamp SK8
aluminum plate
extruder unit
liner rail shaft clamp SK16(for fixing extruder)

attach Z_axis_elevator_module to X_axis_Stepper motor_assy

Then I attached Z_axis_elevator_module to X_axis Stepper motor_assy.
Materials as following....

aluminum plate
aluminum elevator block
brass nut for lead screw
liner motion ball bearing slide unit JPF-3D-XSZC

assemble XZ_axis_assy and Base_unit

Next I assembled XZ_axis_assy and Base unit. 

attach Y_axis_timingbelt, heatbed_unit and XYZ_endstop_SW

finaly, I attached Y_axis_timingbelt, heatbed_unit and XYZ_endstop_SW to Base_unit.  
Materials as following....

GT2 Timing Belt
Y_axis_timingbelt_holder
grass platform(Anycubic ultrabase)
Heatbed
Endswitch for RepRap

wire up XYZ steppers, endstops, Heatbed, Hotend, and fan

wire up XYZ steppers, endstops, Heatbed, Hotend, and fan on Ramps 1.4.
Materials as following....
genuine Arduino Mega 2560 Rev 3 Ramps 1.4 shield A4988 stepper motor driver Full Graphic Smart Controller AC/DC Converter AC110-220V ⇒ DC12V 10A

Oops!

I forgot to attach Extruder unit. orz Now It's put on the top of Base frame.
