Estes's Fin Alignment tool is really cool, but costs like $20, which is a bit steep if you have a club or school class trying to build a dozen rockets at the same time.

I plan to add some photos of it in use in a bit...

So I printed some Fin Alignment guides for 3, 4 & 5 fin rockets using BT-20 and BT-50 tubes. They take a little while to print, but way cheaper than buying a bunch of "real" tools.

Don't forget to check out L3-G0, my completely unrelated working full size Lego R2-D2 on
