Mark,

The area under the launch lug on the fin-can is sealed by the brim that the 3D printer software uses to adhere the part to the printer bed. It is only 0.36mm thick in this case and is easily removed. The color is a red ABS filament made by Vilarox that I have been using for duplicating the Centuri nosecones, it close to the original Centuri red orange color but not quite.

If I ever get a good print of this fin-can I will ask around $15.00 for the printed part (depends on the plastic). I have been asking $8.00 for shipping so the whole set; nosecone, coupler and fin-can will be $29.00 or a total of $37.00 with shipping. I just paid $32.00 for an Estes Eliminator Kit (#1950) that contains the nosecone and fin-can so I am not sure if I want to sell the fin-can for less to compete with that price.

I am currently working on getting a good print with a red PLA filament for the fin can. So far I am having issues switching my printer from ABS plastic back to PLA plastic.
