That’s the problem, I have been unable to find 2mm thick spacers. The designation of the spacer is M3, which is defined as an outer diameter of 7mm, an inner diameter of 3.2mm, and so far have only been able to find .5mm ones in my local stores. So unless it’s acceptable to stack .5mm spaces to make a 2mm one, I’m stumped.You can see from the 5mm spacers what diameter they have. You can simply use this as a guide and then buy 2mm high ones from the DIY store. Basically, it is only important that they are exactly 2mm high. No 2.1mm and no 1.9mm.
