The making of 'Blok Vacuum'

On a drizzly Sunday in January, I was playing with LEGO® with my sons. Always a joy to make something together. Cleaning up, on the other hand, is often something that she, and I, often dislike. This is how the idea arose to make tidying up more fun. 

I then drew a first prototype in a 3D drawing program and printed it with the 3D printer at home. The first version with some minor tweaks already performed surprisingly well. And it was lovely to see my sons having fun cleaning up the LEGO®. A new game had emerged; knock over the lego box, vacuum it up, and knock it over again.
