The file 'Updated Nerf Barrel Spacer 3D Printer Model' is (STL,stl) file type, size is 19.7KB.
Barrel spacers of 0.4, 0.6, and 1mm thickness. I've found that one of these almost always fits snugly for any given blaster and barrel attachment.
I recommend printing two of each.
Using the right spacer will completely eliminate wobble, making the attachment feel like it's a part of the blaster.
Using these completely changed the feel of barrel attachments for me. I'd consider these absolutely necessary for anyone using barrel attachments.

I found these a little thin for some attachments (requiring multiple to be stacked), and 0.2mm layers are more convenient to print. All I've done is make them thicker and add more description.
