Here's another 3D model you can download for free from Thingiverse and print on your 3D printer.
This is an upscale of the BT-50 simulated nozzle (Estes Part No. 072665) that is designed to fit Estes and Rocketarium BT-80 airframe tubing.

There are three models that will either fit a 29mm or 38mm motor mount tube:

1) No shoulder,
2) Short shoulder (about 12mm tall or 1/2 inch),
3) Tall shoulder (about 25mm tall or 1 inch).

GREAT stuff, JH! I just downloaded ALL of your rocketry related files and will be printing a tailcone for a BT-80 rocket I've already built.

I got 404 Errors trying to download these:

Hi Winston,

I just checked those links and they seem to work for me both logged in to and out of my account on Thingiverse. Not sure why they aren't working for you. You might empty your browser cache and try again.

FYI: Those three links work for me, too.

The links work for me as well, but when I try to actually download I also get the 404 error.

This is one of the download links (by clicking on the 'Download all' button on any of the three links).

I downloaded both files with no problems. I think the website might be having some problems is my best guess.

https://www.thingiverse.com/thing:3829871/zipYes, I failed to make it clear that it was the attempt to download the zipped files that gave the 404s.

This same just happened to me with a supplied link to a Thingiverse item given within an electronics forum post and I was told that this was for some reason happening more frequently recently at Thingiverse and the workaround is simply to click on the "Thing files" box and click to download the STL files individually and unzipped. Works fine.
