I too use this baffle in a CF tube and it is quite effective. I am just getting back into printing so I have nothing to offer you but I would like to see a file for this as well.
Bruce,What is special about the Crosman baffle design is that it is simple to manufacture via plastic injection molding. The request was for a replacement with better performance. As it turns out, for a 1.1" ID CF tube, rather than the Crosman insert at .89". The latter had been wrapped in felt to make it snug in the 1.1" ID tube.I did a custom design for the OP, despite his forced absence from the forum. If you can find your CF tube, I would be happy to do a design for you. What qualifies me? Read my recent contributions to the Notos thread that precede the commentary about it, linked below, as an example: https://www.gatewaytoairguns.org/GTA/index.php?topic=206735.msg156438137#msg156438137
Regarding the Crosman baffle... they work fairly well. About 3 years ago I ordered 10 of them direct from Crosman. Cost was ~$2 each with $4 S&H for the entire order.Baffles not optimum but as stated easy and cheap to injection mold this design. Drawing not quite correct. Here are more images to help with details.Edit: I place an o-ring into groove on threaded end and press fit the baffle into a trimmed piece of aluminum tubing. Snug fit so no need to secure aluminum to baffle for my low energy needs. For higher energy applications I drill a couple small holes in the aluminum tube and thread a couple small screws into a "meaty" section of the baffle.
