Multilayered model assemblies

A model assembly of stratified planar layers comprising:

• a first layer having two sides, said first layer having a profile and containing a bore;
• a second layer having two sides, said second layer having a profile and containing a bore, wherein the bore of the first layer and the bore of the second layer are aligned and perpendicular to the first layer and the second layer, wherein the second layer is comprised of multiple sublayers and the sublayers differ in profile shape;
• a first connector of suitable length extending through the bores and rotatably connecting the first layer and second layer, said connector having a central stem with heads at opposite ends, said connector being adjustable in length to impart a clamping force on the lavers when tightened, wherein the first layer and the second layer slide against each other in adjacent parallel planes when rotating about the connector stem and whereby reducing the length of the connector impedes rotation of the first layer with respect to the second layer;
• a third layer, said third layer having a profile and containing a bore, wherein the first connector extends through the bore of the third layer, connecting the third layer alongside the second layer, wherein the first layer and the third layer rotate about the connector stem with respect to the second layer;
• an appendage layer, said appendage 1a having a proximate end and a distal end, said appendage layer having a proximate bore at the proximate end, said proximate bore in alignment with and rotating about the second connector said appendage layer rotating in the same plane as the second layer;
• a distal bore at the distal end of the appendage layer, said distal bore fitted with a third connector;
• two or more extremity layers each having a profile and a proximate bore and a terminal bore, said proximate bores of the two or more extremity layers in alignment with and flanking the distal bore of the appendage layer, said extremity layers fitted along the third connector and rotatably connected to the appendage layer, said terminal bores distal to said proximate bores along the extremity layers;
• and
• a filler layer in contact with and fitting between the extremity layers, said filler layer having a bore in alignment with the terminal bores of the extremity layers, said filler layer and the distal layers secured together with a fourth connector,
• wherein the filler layer further comprises a stop in the same plane as the appendage layer, thereby limiting rotation of the extremity layers with respect to the appendage layer.

A model assembly of stratified planar layers comprising:

• a first part with multiple layers, said first part having a primary layer containing a “T” shaped void, said “T” shaped void having an end opening and at least one side opening;
• a second part with multiple layers, said second part having a primary layer containing a “T” shaped void, said “T” shaped void having an end opening and at least one side opening;
• a connector having a rotating washer block at each end, said connector adapted to fit through the end opening of each primary layer;
• and
• a secondary layer fastened against the side opening of the primary layer of the first part, and a separate secondary layer fastened against the side opening of the primary layer of the second part, thereby capturing the washer blocks in the voids of the primary layers of each part, wherein the primary layer of the first part is co-planar with the primary layer of the second part and whereby the first part is rotatably secured with respect to the second part.
