This is a shim used to properly position the cabinet frame.
It's designed for assembling an IKEA LACK table. The frame isn't flush with the table; there's a 1.5mm offset. This tool ensures a vertically aligned frame when constructing a 3D printer enclosure.
I printed it in PLA with a layer height of 0.1 for precision and a 20% infill.
