My goal is to archive and share the work of my math students. Scanning their tests, quizzes and projects and then archiving them in a shared Googledocs folder. Scanning all this work would be too much for one teacher so I require my students to do it themselves by using their own smart phones or this "classroom" scanner. The advantage of this design is that the ipod is secured and that it is on a wifi network (so students don't need to use their personal data). There are many good scanner apps that are both free or have pay versions. I am using Scanner Pro. I also have installed "airscanner" (found here - //www.qrayon.com/home/airscanner/). This makes the stand into a wireless document camera that transmits to a browser.

The green model is probably my last as it does the job as needed. The advantages of this last model is the lack of walls to block access for books and magazines and that it is the strongest of all prototypes.

The cost of the acrylic from Amazon and estreetplastics is around $25. The ipod touch - 5th generation was purchased on eBay for $100.

Step 1: SVG File for Laser Cutter

The pieces are grouped together for four (4) pieces of 1/8"x12"x12"x1/8" pieces of clear acrylic, one (1) piece of 1/8"x12"x24" dark acrylic and one (1) piece of 1/8"x12"x12" plywood. Link to SVG file.

Step 2: Laminate the Arm Pieces

For added strength, the arm pieces are laminated together using SCIGRIP 3 Acrylic Solvent Cement. I only used two full sizes arms so that only four pieces of clear 1/8"x12"x12" acrylic are needed. I don't think the laminated pieces that have been cut reduce the strength by much at all.

Step 3: Laminate the Dark Acrylic to the Wood Bottom.

I used wood glue spread evenly with a popsicle stick.

Step 4: Connect Arms to Base.

I needed to file down the slots with a rasp to make them slightly wider. Then I applied plenty of SCIGRIP 16 10315 Acrylic Cement to make a strong connection.

Step 5: Add the Front Cross Piece

This makes the scanner level. Pieces fit snugly but I still added some SCIGRIP 16 10315 Acrylic Cement.

Step 6: Glue the Top Piece

Glue the flat connector piece with finger joints to the arms using SCIGRIP 16 10315 Acrylic Cement.

Step 7: Secure the Ipod

Use bolts to secure the ipod to the top. I added two blank layers so that the stand gained a bit more height (necessary to capture a full 8.5" x 11" piece of paper.

Step 8: Add a Rubber Band.

This keeps the charge cord out of the way.

<p>Hey. This is a great design. I thought about making something like this for years and now I think I finally will.</p><p>A suggestion. I think I'm going to add some soft lights and disable the flash. With some trial and error I think this will provide a much more consistent image. </p><p>Nice instructable! </p>
<p>It looks like a solid scanner. Thanks for sharing how you made it!</p>
