thingiverse

Last updated on November 11, 2013, at 5:30 PM EST, the Digitizer Illuminator's version is v3.3. When wired with a 5mm white LED, it offers customizable lighting options for your 3D scans. For a complete guide, bill of materials, and assembly instructions, click on the 'Instructions' tab! The update includes: 1. A stronger, redesigned top clip to prevent cracking. 2. Larger holes for running wires from the LED to the housing. 3. Resizing of the tab slot on the bottom of the housing. 4. Changing the back panel dimensions to fit the new housing. 5. Resizing of the 9v battery compartment for better wiring. 6. Revamping all screw holes. If you build this, feel free to share your experience or ask questions/comments/feedback! The Digitizer Illuminator clips onto the MakerBot Digitizer's crossbeam and provides variable light settings for improved 3D scan quality. To assemble the Digitizer Illuminator, you need: 1. A 9V battery. 2. A 9V battery plug. 3. A 100 ohm resistor. 4. A 5mm LED of your choice color. 5. An LED holder (SparkFun PN: COM-11147). 6. A 10 kOhm rotary potentiometer (SparkFun PN: COM-09939). 7. A black knob (SparkFun PN: COM-09998). 8. Two 1/2" 4-40 screws (SparkFun PN: PRT-10452). 9. A medium rocker switch (SparkFun PN: COM-10727). 10. About 12 inches of hook-up wire. Here's how to assemble it: 1. Mount the LED in the LED holder and solder 4" leads to its anode and cathode. 2. Feed the LED leads through the LED mounting hole on the "Housing" file, then continue feeding them into the larger compartment's hole in the lower left corner. 3. Screw the LED Holder into the Mounting Hole on the Housing. 4. Solder 2" leads onto the Rocker Switch and pass the wires through the front side of the square hole on the Back Panel. Clip the switch into the square hole, with the counterbore screw hole facing the same side as the potentiometer. 5. Mount the Potentiometer on the large round hole on the Back Panel. 6. Pass the 9V battery plug's wires through the shelf's hole in the large compartment of the Housing, with the plug facing outwards. Tie a simple overhand knot in the wires for stability. 7. Solder the circuit as follows: 9V Battery → Rocker Switch → Potentiometer → 470 ohm Resistor → LED Anode → GROUND. 8. Attach the knob to the potentiometer and plug in the 9V battery. 9. Insert the Back Panel with its tab into the slot on the back of the Housing, ensuring it fits flush against the Housing. Secure it with a 1/2" 4-40 screw. 10. Attach the LED Panel to the Housing in the same manner. 11. Mount the completed assembly on the left side of the crossbeam of the MakerBot Digitizer, ensuring the LED is centered behind and above the camera lens. When the camera filter is closed, the right side of the Illuminator should be flush with the left side of the camera filter. 12. Flip on the Rocker Switch and enjoy your variable light source for your MakerBot Digitizer Desktop 3D Scanner!
