I wanted to be able to have my drawers fixed to the desk so that the drawers could be pulled with moving the unit and also be able to remove drawer tower easily. A set fits a half width unit and 2 sets would be required for the wide units.
1- Glue four 6*4mm magnets into the recesses on each part ensureing the correct polarity so that any upper part can fit on any lower part.
2- The lower parts are then screwed to the desk.
3- The upper parts slide onto the bottom of the drawer units with a tight fit.
The author remixed this model.
Addition of magnetic base
