* 3D Printer

In order to have some pieces for the automation projects, like custom boxes for small and integrated prototypes, a 3D printer was built.

It is inspired in some videos starting in this link: How to build a RepRap Prusa i3.

List of materials and budget:

- 3D printer full acrylic frame mechanical Kit for Reprap Prusa i3 DIY, $ 149.95
- Ramps 1.4 + A4988 + Mega2560 R3 + Nema 17 Controller Kit, $ 189.99
- MK8 Extruder Nozzle Print Head , $ 45.95
- Heated Bed Tempered Borosilicate Glass Plate, $ 15.99
- Filament Outlet White PLA 1.75mm Filament 1kg, $ 21.97
- 1 x 10K ohm NTC Thermistor (local market), $ 0.80
- PC ATX power supply 12VDC-25A (local market), $ 18.00

The total cost is: $ 442.65






The arduino source code: Marlin code

The OpenSCAD program is used to create the costumed boxes with holes.

In the link project_box, there is a OpenSCAD project box.
