Nerf Blunderbuss

UPDATE 1:

added an inner locking ring and a singled barrel. (PLEASE DO NOT SHOOT LIVING THINGS WITH THIS.) A singled half dart out of this blaster will clear 300FPS easily. It's fun for plinking cans and stuff. More smaller shells incoming that will actually be useable.

Also added a fatter version of the 38 dart barrel for anyone complaining about breaking the original. For anyone with durability issues I recommend printing with higher temperatures / smaller layer height.

This is a blunderbuss attachment for a dodgeball blaster that holds 38 full sized nerf darts (or 76 half darts!)

You will need to make some slight modifications to the dodgeball blaster. I do not have pictures but it's easy.

There's a tube/air restrictor that slides partway out of the air hole. DESTROY AND REMOVE that moving part. Flush Cutters and some caveman brain can get it out. After that, look down through that big hole at the plunger. It has a hole in the middle of it. Seal this hole up with DevCon.(I used a screwdriver to apply it down in there, be careful not to glue the plunger to the sides of the blaster) Let it dry for a day. That's it, it's now ready to fire for real.

Print out the locking ring and use a generous layer of glue to attach it to the outer red barrel on the blaster, make sure it is flush and air tight.

Then lube up the Blunderbuss attachment and it should just slide/rotate on.

You can print multiple barrels to carry reloads!

There is a mix of skewed and straight barrels, between 0 and 3 degrees.

Everything is designed to print without supports
