Below is a list of build instruction logs that will instruct you on how to go all the way from sourcing your components to printing the parts, and constructing your very own raman spectrometer!

To begin, you will need some tools..  Pretty much every section requires similar tools.  If a section requires a special tool not listed here, it will state that and show you which tool is appropriate.

Tools Required:

• 1. Needle Nosed Pliers
• 2. 1.5mm Hex Driver
• 3. 5/16 Hex Driver
• 4. Philips Screw Driver
• 5. Precision Tweezers
• 6. Nitrile Gloves
• 7. Cotton Gloves
• 8. KimTech KimWipes

3D Printed Part Guidelines:

Printing the 3D Printable parts will take you probably about a week. The spectrometer portion alone took about 15 hours on my XYZ daVinci 1.0 printer.. The 5.25" Drive tray takes about 10, and most of the other parts are about 6 or 8 hours.. Print in high enough quality to make sure the parts end up solid enough that they won't crumble in your hands..use 30-50% density... Supports are a good idea and the spectrometer really should be printed with the inside facing the floor. I managed well with .2mm height, you might want to try .1 or whichever is best for your printer. All the parts have been designed for use with ABS plastic and I would recommend using black ABS filament.  For parts with beam paths, I am investigating different ways to coat the interior for reduction in reflections, etc. For now, if you like you can coat them with a flat black paint..this will help keep the noise floor down.

All of the 3D Printable objects are located in the gitHub repository.  They have been created with openSCAD and can be modified, etc.  You can view the .STL files and you can download and edit / modify the .SCAD files as well.

Following Instructions:

Each section of the raman spectrometer system is divided into separate build logs to make it easier to find a section and keep the flow.  You'll see each section has a "LET'S BUILD IT" graphic..

You can click on that and it will take you to the appropriate instructional build log associated with that section!  At the end of the instructional build log, there will be a link to return here...or you can just close the tab and this tab should be here waiting!
