I've designed two different dust port options for the Master Craft router table.

1. 2 1/2" dust port extension: Extends the 2 1/2" dust port past the table to make it easier to slide the hose over the dust port. Avoiding very small tolerance between the table and dust port.
2. shop vac hose adapter: adapts the 2 1/2" dust port to a shop vac hose size so you can directly hook up a shop vac to the dust collection port.

Both models may need a small amount of sanding on the inside of the part where it slides over the mastercraft router table dust port. This depends on the quality/settings of your print. The flat spot on the model is the bottom and should be narrow enough to fit betwen the dust port and the table.
