CAUTION:
Children should ask for parents advice before using drilling and cutting
devices! First you need to drill a hole from the bottom side
into a standard LEGO brick. Use a 4.5 mm drill. The tube in the
brick helps to center while drilling. Then you can cut a M6 metric thread
also from the bottom side. Finally you can use a M6 metric screw
to mount anything you want.
