Over the course of the next several or more weeks I'll be posting rail buttons and guides plus launch lugs and stand offs that you can download from Thingiverse.com for free and print on your 3D printer.

The first design I present to you all is just a standard 1010 rail button.

There are two files you can download - one with a recessed area for screw heads and one without for button or pan head screws.

1010 Standard Rail Button

1010 Standard Rail Button Recessed

The second design is also a standard 1010 rail button, but the edges on the button are rounded. Same recessed and non-recessed tops.

Can I suggest making the ID on the airframe side a little wider to accomodate the riser from a TEE Nut? The ones from Apogee have this feature, and it makes it great, as the tee nut can come all the way through the airframe and into the underside of the button...
 
Good deal.

This is a great idea. That's how I do mine but I think maybe I just use a smaller t nut.

Dimensions of the Tee Nut?
 
If you are 3D printing these then it would be possible to add a contour to the top.,flat surface of the aero rail button (instead of it just being flat). I don't know what effect it would have on drag but I bet it would look cool. The rail is gonna limit the height and possibly the contour shape.

Whip one of those up and I'd be tempted to fire up the printer.
 
Can the top surface of the aero button be contoured instead of flat? I'd guess the height, and shape might be limited by the room inside the rail. There may not be a drag reduction but I think it would look cooler than the flat top.
 
If you need the posts edited after 24 hours, let me know and I can edit them for you.
 
If you need to add links to thingverse files later. I can edit the above post and add this links later once you add them to thingverse.
 
here's a rough idea. see attachment

What does the longevity of these look like compared to acetal/delrin/nylon buttons made by subtractive machining methods?

I have no idea. ABS is probably the best material you can print for this application. You can also print with nylon, too, if your printer can handle it.
