I made a case to protect my darts when taking them somewhere. Here are some more images. The case was made to fit a specific model and it’s not very parametric till then end, so I’m afraid it’s not super useful for others.
It was made in #FreeCAD 1.0 which was super smooth!



- That’s really cool. Are they held snug? Will they fall out? - They fall out. For now I use a rubber band around the case but I don’t like that solution too much. The initial idea was to put a rubber band around the “waist” so that they would be held there. Unfortunately the rubber then doesn’t touch the dart. My current idea for a fix is to make a clip that pushes against that darts sideways through the holes. - If you ever printed a 2nd iteration, you could created a space for an oring to sit for each dart so it gets lightly held in place by friction - I was going to say to just make the end slightly undersized so when you push it all the way in, it gets held in by friction. - Giggity. 
- It’s a good idea but I’m sceptical about anything friction to hold the darts. The problem is that they have very sharp machined rings that make them very non-slippery to the fingers. I’m pretty sure those rings would file off anything they slide against very quickly. - The steel tip does not have this problem though, so adding some part that pushes against the tip might be the solution. Alternatively, i could also make the part that houses the flights be somehow spring loaded and squeeze them. 
 
 
- If you wanted to try to make your original rubber band idea work, you could try moving the central dart up slightly so that the rubber band forms a triangle shape and adjust the contact points between the rubber band and the darts to be at each corner of that triangle - Yeah, I think I see what you mean. I’m very plastic conservative so I hope I can go without printing a second one, therefore the clip idea. Also the clip is a bit more practical better looking. - That’s fair 
 
 
 
 
- I was lije like “damn those are some beefy darts, where’s the case?” - before reading the title I thought OP was trying to turn the back of the dart into the tip of a mega dart
