I created a Lego themed taller desk light base in order for the light (Ikea Terital Work lamp) to rise above my 32" monitors. It reuses the desk clamp pieces that came with the light. Should work with any adjustable desk light that has the stick end that is 13mm OD or smaller.

It just sits in the top hole in the lego block. The block is 115mm tall and to scale. Can also be stacked with other same Lego block prints.

The light grey piece in the attached images is the ikea part for reference.
