Here's the RFBC-500 Avtomat Pushka (sorry, my computer-translated Russian is terrible), an Automatic Rifle Cannon (RFBC proxy).

It's available in both Right (A) and Left (B) versions, with the main weapon body having a choice of stick or drum magazine.

Also, one of my heavy stubby gatlings is incorporated into the design. That asymmetric part of the design is a nice feature, in my opinion.

A pair of weapon arms, long and short, are supplied, as well as upper arms at a variety of angles for magnetization.

I glue the ball and sockets together, then glue 12mm x 2mm magnets to the bottom of the upper arm.

An 8mm x 2mm magnet will fit in the face of the main weapon body. I usually glue in washers in the barrel section. 4mm inner diameter/9mm outer diameter washers usually do it, or #6 washers.

You can use opposing magnets in the weapon arms (remember opposite poles) or stacks of washers.

Enjoy, and thanks again! More good stuff to come.

Best,JBR

3D PRINTING SETTINGSNo supported versions, since every machine and material combination is different.

I print barrels and other cylindrical objects perpendicular (90 degrees) to the print bed for best results.
