Hello everyone! These are three different sizes of 3D printed magazines for use with Buzz Bee shells.  Back when I was working on my Buzz Bee Torrent parts,  I discovered that the legendary Daniel Beaver had designed some printable Buzz Bee shells! They work great in all the Buzz Bee blasters I have that use shells, but as I searched around online more, I found that nobody had yet designed a printable Buzz Bee shell magazine. I figured if I was looking for one, then other people probably were as well, so I decided to try my hand at making one! 

My goals for this project were to make the magazine parts as easy to print as possible, as well as make said parts as easy to assemble as possible.  In the end, each magazine body is printed as one solid piece made to flex open to allow for the drum spring and follower to be inserted. Then, the magazine catch piece can be slid into the front, and the body can be screwed together with either two 2-56/toy screws or M3 screws.  The body should be able to be printed without support, but there are cutouts at the base of the magazine bodies to allow for supports if they are needed. 

In my testing, one drum spring was sufficiently strong to raise the shells in both the 4 and 6 shell magazines. But, for the 9 shell magazine, one drum spring wasn’t reliable enough for my liking, so in that magazine I included space for two drum springs rather than one.  For all of the magazine sizes, but especially for the 3 shell magazine, I would recommend a light sanding on the edges, as well as some lubrication to help the follower slide smoothly inside of the magazine. 

I would recommend you use any extra screws you have on hand, but in the event you want specific screws to look for, here are some approximate screw lengths:

2-56/Toy Screws: 1/4” Long

M3 Screws: 6mm Long

These models are not exact copies of the Buzz Bee Magazines, but hopefully they are a close enough imitation for those who are interested. I had tons of fun working on this project, and I hope everyone else enjoys them as much as I have!
