Dart fins

This version has 10-32 thread on the end to screw into a typical dart barrel. The threads didn't print super well, but I screwed it into a dart barrel while it was still hot and it worked very well.

***Edit

I have uploaded a new version with slightly stronger thread because I found that it was snapping off on impact. I will try printing a couple like this, and report back. If they still break, I will redesign them with a hole that a piece of threaded rod can be inserted into. I also thinned it down and shortened it some to make it lighter. .***

***Edit 2

The current part looks like a winner. I will have to play a couple games with them before I can say for sure, but they certainly look and feel better than previous versions. If anyone prints them and has any input, please comment. I also replaced the Solidworks file that I had previously forgotten about***

***Edit 3

I have uploaded a new version that is split and printed flat. I printed with PLA and glued with couple drops of crazy glue. This is far stronger than the original version. Simply print side 1

and side 2 and glue together. I screwed the two pieces into the dart barrel before gluing to ensure proper alignment,***
