Extend your Ikea Lack tables with this smart extension. The extension adds an extra 30mm in height to your table, which is ideal if, for example, you are building an enclosure for your printer and need a little extra height. There is also a channel for an approx. 40mm plaster/wood screw for extra stability, but use of the screw is optional. You can download the STL file if you want to use the following parameters, or go to the OnShape link below if you want to customize them.
