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!
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.
