HAH another Rue's first!
Control Pendant for cnc machine.
This is made in several stages with openscad.
Two shapes are made, an inner and outter block,
the inner block is subtracted from the outter one to yield a 2mm shell
The shell is cut in half
each half is modified with stuffs.
This uses a standard 1602 lcd, but you will have to customize the encoder and keyboard, mine came from a bank machine and a process controller for a paper mill, so you cant find the same ones.
Look at teh openscad stuff to understand the dxf.
dont just print all the stls!
