cases for experimental electronics

My houses/cases for experimental electronics. Standard boards 160x100mm are fitting as front and also as button.
So you can place potentiometers, switches, variable capazitors to the front and your pcb to the button. You can change things with ease, though you have a very stable and good locking fnctional device.
There is a stabilizer, which you can glue or scew to the top of the housings between left and right pole, if nescessary

case 1: front can hold even Boards with 160x200 or 2 boards 160x100mm (2 floors?)
case 2: normal case
case 3: special for heavy things (power supply?)

Made with Open-Scad, source-files also downloadable.
