Exhaust port replacement spacer Stepcraft CNC

There is a small plastic spacer under the screw head that tensions the exhaust port for the HF-500 and MM-1000 spindles. Since there is a 3mm gap under the spacer, any excess torque on the screw will flex the plastic spacer and snap it.

This is a replacement spacer that has an additional area extending down into the gap to fix any flexing and breakage issues. Designed in Solidworks.
