This was designed as a 3D print and the features are not difficult to print.

That means this a real easy print (at least for me) no hassle with support or a raft.
To make it more reliable I did add the little circles on the ends so that the material would have a better chance to print without loosening from the buildplate.

I chose the distance from dart to dart at 30mm to make it look nice and so that they would have enough room with the flight on, the depth of the 2.5mm hole is 23mm.

For me I added the second feature to hang my darts case with extra equipment.
If you would like for me to remove thing because you don't need it feel free to ask in the comments of this part!!
