I do Printer refurbishing and there were several salvaged parts from fixed printers hence thought to use them to build something new and here it is. I had parts from Ender 3s whose Heated bed died, base frame screws went free, a board with a blown stepper driver, etc.

Parts used from Ender 3;
- Both the side base profiles are used as front and back base
- Both the Z profiles are used as left and right base.
- The X-axis profile is used as X profile
- 6 count Z-axis Wheels as Y-axis wheels.
- 3 Count Tool Wheels as tool wheels.
- Control board with modified firmware.
- LCD.
- Existing PSU can be used with a 12v 3A Buck convertor for Laser.
- Most of the screws.
- Peeled off Magnetic sticker from Bed.

Parts bought new;
- 12v power supply (if you are not using existing PSU)
