Step 1 - Cut the Wooden Planks
Cut wooden planks 12 millimeters thick, according to the dimensions indicated in the attached file. [mm]
Step 2 - Cut the Mirrors
Cut the mirrors 4 millimeters thick, according to the dimensions indicated in the attached file. [mm]
Step 3 - Cut the Double Tape
Cut 6 double tape strips of 500 millimeters. If possible use a outdoor double tape
Step 4 - Assemble mirrors and planks
Assemble the mirrors and the wooden planks with double-sided tape according to the attached image. Please note the shutters are asymmetrical
Step 5 - 3D Print concentrator Holders
Print the attached 3D files, preferably in ABS

Step 6 - Assemble the Sun Collector
The sun collector made is made of tempered glass and can provide temperatures above 250°C
To fixe the tube tighten the screws of the 3D printed front holder
The overall size is 660 mm (overall) X 127mm outside diameter. The approximate interior dimensions are: 584 mm X 101mm inner diameter.

Step 7 - Assemble all pieces
Assemble all components with wood screws and 2 3D print filaments.
To assemble the shutters, first drill the hole for the screws to have a pivot effect.
Step 8 - Use the sun concentror
To use the solar concentrator, it is advisable to use temperature probes.
The concentrator should be placed with the solar collector perpendicular to the sun light (12h - south).
The shutters should be adjusted so that the maximum light is projected onto the collector, as shown in the picture.
