The project consists of 4 main plastic parts:

1. Fixing plate (Laser cut from an Acrylic sheet 3 mm)

2. Cover for the Arduino (3D printed)

3. Cover for the mechanism (3D printed)

4. The mechanism itself (Laser cut from an Acrylic sheet 3 mm)

After I designed these parts on SolidWorks, I exported the files into two types:

1. DXF files for the laser cutter.

2. STL files for the 3D printer.

In this step, I'll talk about the laser cut parts and you will find all the dxf files attached.

For the fixing plate:

It consists of two part, the big Acrylic sheet and the small circular dots.

I used 3 mm Acrylic sheet to cut the big part then I used 6 mm Acrylic sheet to cut the small circular dots. After that I used super glue to fix them together.

I will use these dots to fix the covers on the fixing plate like the LEGO parts.





For the mechanism parts:

I believe in the concept of "Do not reinvent the wheel", so I followed this great instructable.

In this instructable you will find all the required details to make the mechanism parts and assemble them together.



Now, Lets warm up the 3D printer :D
