I'm trying to raise my desk by 3cm so it matches the height of the chest of drawers next to it.
It's corner desk made from furniture board (18mm thick) with 2 side boards as legs and a corner joint (see below).
Originally I thought just buy some wood and attach with metal plates but I don't really have the tools at the minute to cut the wood to size (don't want it sticking out too much). Ideally I want some adjustable feet that I could screw to the side of the board as its not really thick enough for those standard adjustable feet which drill in.
Any ideas on the easiest way to do this?
