Abstract
A frame may comprise a plurality of interlocking tab-and-slot frame members forming a three-dimensional structure. A removable stringer may be designed into one or more of the interlocking tab-and-slot frame members. The stringers may be removed after positioning and welding of tab-and slot frame members together. Notches may also be designed into and formed as additional features of a tab-and-slot frame member. Notches may serve as a guide for bending tab-and-slot frame members and in the creation of tabs and/or slots of the tab-and-slot frame members.
