THE BODY
I found Acrylic + laser cutting to be quite a powerful combination . I prepared .svg files ( using inkscape ) for the body parts of the machine and got it laser cut from outside.
The acrylic was 8 mm in thickness .
I didn't put holes for the motors initially . I drilled it myself to allow manipulation of the position of the motors.
I cut angle brackets from aluminium and used unbrako screws to hold it all together .
