When creating my MOC, I have found that I need to build exactly 5 LEGO units (2.5 plate heights) above a plate, both planes being studs up. However, I can’t seem to find a method to get this height difference. Does anyone know of any way to achieve this, especially in a small space? I would also accept any techniques with modified LEGO, so long as the modification is convenient (simple cutting/gluing).
