-Drill through the plate that is standing up into the side of the plate that is lying on the table, approximately halfway along the length of the plate. 
-Countersink the hole and add a screw. Add two more screws about 3cm from each end of the plate.
-Repeat this for another pair of plates.
-Lay the two pairs on the table and put another 45x10 plate between them. Align the new plate with one of the edges.
-Clamp the plates down and use 6 screws to attach the cross plate to the two corners.
-Place the 3mm spacer on the table, and put the last remaining 45x10 on top of it.
-Stand the remaining plates on end, and place them on top of the new plate. Use 8 screws to secure the bottom plate to the rest of the frame.
-If you want to, place the 47.5x10 plate on top of the entire structure and attach it with 6 screws. This is a convenient place to mount accessories, such as a filament roll holder.
