Find a large rifle ammo case, I got this one at Academy for 2.99.

I had to cut off a loop normally used to allow a lock on the case.

Drill Small holes to fit the screws you have handy.

Drill larger holes so the head of your screw fits through.

I added a small layer of craft foam to make the darts fit snugly.

Paint as needed to match your blaster.

Use the case as a guide and drill two small holes in the shell, again sized to whatever screws you have on hand.

Mount to your blaster. Cheap and easy 20 dart "quiver".
