Figure 4 is an example of how the jig will clamp the test specimen. The green planks are aligned as seen in Figure 3. The main tray shouThenwill be placed flat on a table. Then, a flat board (like a piece of plywood for example) will be placed on top of the specimens and weights will be placed on top of the board to apply downwards pressure on the z axis (purple). There will be four longer boards, two per axis, that run parallel with the sides of the specimens on the x and y axis. The spacing between the specimens and the brown rectangular jigs, seen in Figure 4, These boards are in place so that pipe clamps can apply pressure from the sides (red). The idea is that the blue square-shaped pieces will ensure that the test pieces line up properly under clamping force. It is possible that more thin brown square pieces may need to be added in the middle section. Nine of these specimens can be lined up at once inside of this tray.

Use AutoCAD to create layout of pieces that need to be laser cut. In total, this needs to include 4 copies of each component of the tray.
The idea behind this is to stack four 1/8 inch thick pieces of fiberboard to create a 1/2 inch tall tray.
Minimize the area occupied by the pieces. This is because the 3D Print Centre charges per square foot.
All vector cut lines should be 0.00 units line thickness and all raster/engraving lines should be set to a minimum of 0.25 units.

Turnaround time is 2-3 days.
Use wood glue to bond two copies of the same part.
Apply a thin strip of wood glue along the entire piece.
Clamp down both pairpairs of fiberboard pieces for curing. This takes 24 hours according to the glue manufacturer instructions.
After the pairs of fiber board have fully cured, repeat steps
