RPM Mechanical manufactures a complete range of mounts specifically designed to control/reduce vibration.

The part number VMB-0912H has been used successfully quite often for mounting small electronic products on mobile equipment. It is 4mm, so would fit the CR0303.

Misumi also offers these types of mounts. They have a 5mm unit (Part number BGONA12160) that could be used with our R360 controller range; it has been used with our R360 product but does not offer the same level of vibration reduction as the RPM unit. This is primarily because the spring rate is about 3 times as high.
