I think they make different types, either Aluminum or Steel, and different thickness for different temperature ratings. They also have high-temp BBQ paints as an option.

The foil tape is also a cheap option for decorative metallic bands on rockets, compared to Monokote, etc.

How about brushing a coat of epoxy onto the inner surfaces? That should at least act like an ablative coating. I typically use CA on cardboard motor tubes if they are standard tubes, figuring I might be lucky and actually have the rocket last long enough to worry about motor tube burnthru.

I am no longer using PLA filament for my 3D prints; instead I am using ABS which I find to be less brittle and much more heat and warp resistant. ABS, at least in my experience, is much easier to sand smooth than PLA and accepts paint and glues made for plastics well. The attached picture is is of some ABS parts that I recently printed. I am trying to clone an Estes Geo Sat LV. I got the files for these 3D plastic parts from Thingiverse:

The key to printing with ABS was to use the right extruder temperature, I had to do a lot of trial and error runs before I found the ABS plastic's optimal print temperature. Note that I do not have an enclosed printer as is generally reccomended for ABS filament. I also haven't had any issues with the ABS filaments picking up moisture. I am using both Hatchbox and Solutech brand ABS filaments and have got great 3D print results with both of them.

Have you tried 3D printing with ABS filament? I am interested in hearing your thoughts and experiences with filaments other than PLA.

I personally have not yet used anything other than PLA, I'm not against ABS, just haven't had the need as of yet. If you want to print the satellite in one shot, I went and did that part also. I wanted it as a single part I wouldn't have to glue together. If you are interested it can be found on my nosecones page. Cone number 26

Ignore last comments I need to do some re engineering on that nose cone. Thanks Teflon for the heads up.
