I have an AD-060 and I cannot fit it into the space meant for it, as it's 3mm too tall!

I think I can fix this problem by removing the feet. Does anyone know how to do this? From what I see they can be removed but they are attached via 3 unusual screws that have bits that expand outwards. So it seems I need some way to crimp them to get to to move through the hole again.

Can anyone help?
