[chbot] 'Printing' an enclosure

Why go so large. 

One of the arduino mini/nano and I2C LCD
display will be much smaller. 

For the display mounting we cut an
oversized piece of clear acrylic, and fitted countersunk screws (ie
between the acrylic and enclosure. 

This got silicone onto the
enclosure, and provided a watertight seal, that was extremely hard to
pull off or poke in. 

This eliminates the 3D printed enclosure, but
does require some neat cutting and filing of the opening.....
