Darts holder, pluggable, stand alone

A colleague asked me if I could print him a dart holder. Of course I said that shouldn't be a problem and if he already had an idea? I recommended the usual websites and he came back with something that looked like a hedgehog. When I took a closer look at it, I realized that the dimensions were not right at all and the part would be huge and it would eat up a lot of filament. Also it was anything but not print friendly. So I tried to design a new and print friendly part which could meet the demands of my colleague and me.
This is the result.
Since I haven't seen anything comparable (free standing) yet it could be that out there someone else will benefit from it as well.
The holder is pluggable and therefore space-saving to transport.

You may have to rework a bit when putting together, depending on how well the printer is set. Otherwise, what always helps with 3D printing, pressure and heat :-)
I am attaching the step file so everyone can modify it for their purposes if they want.
Have fun with it.
