These are all the parts needed to build display arms in various configurations. Here's what you'll need to print:
Two of the arm parts, at whatever lengths are needed given the size of your built kit. Normally you'll want two different arm lengths, so you can make a triangle with the longer side used as a downward brace (as shown in the photo).
Two hex wall inserts, which attach the arm to the Honeycomb Storage Wall.
Five connector A pieces, used for attaching everything together.
One connector B.
One of the attachment pieces. There are different styles to fit different kits, depending on the type of action base connector they need.
