Bt3100 router table "ring" inserts?

[Matt_W]

Hi guys,
I recently mounted my Bosch router under the table on my Bt3100. Problem is, the dust collector on top doesn't do a darned thing because all of the dust and chips fall under the table. I chose to make my own mounting plate for the router, and the hole around the bit is so big that everything falls below. Where can I get those red insert "rings" that you can put in the table to close up the space around the bit?
I chose not to buy the accessory kits and make what I needed...but what other solution is there? Or is there some place I can just buy those rings?

Thanks,
Matt
