    Does anyone have a file for a jig to you on a 3 fin BT55 tube they would like to share? I tried Thingiverse, could not find that size. Thanks.

    Go to the scratchbuilt section and look on page two of the build named Sentinel upscale 2019.

    or use this link

    https://www.rocketryforum.com/threads/sentinel-upscale-2019.152917/

    I downloaded a pdf of a fin alignment guide from payloadbay.com, printed it, copied it to a piece of

    cardboard and using the wooden fin jig had what I think are spectacular results for fin alignment and

    trueness when sighted down the body tube.

    here's a link to the choices on payloadbay.com

    https://www.payloadbay.com/page-Tools.html

    You can enter the diameter manually along with other parameters and get what you want.

    Good luck

    I have used "Payload Bay" many times. It is great. But I wanted to try to print my own on my brand spanking new printer. Thanks.

    I just put this one up:
    https://www.thingiverse.com/thing:4125871

    Having trouble with getting thingiverse to render the stl file though. If you can't pull it from there, pm me and I can send it to you. This is a mod of my 4 fin jig. I have not specifically tested the 3 fin version, but would assume it works well as the 4 fin does.

    I did find the one Charles linked. Have it downloaded, and will print it after this one is done. This printer thing is kind of like Lays potato chips :)

    I'm wondering if Thingiverse updated as the upload process is a little different than a couple days ago. If you click on Thing Files, then BT55_3fin_v1.stl, you should be able to get the file. If that doesn't work, pm me and I can either email it or put it on my ftp.
