3D Scanner
Description
***Please note that this project is created for educational purposes. The project may not be optimal in some ways, and may even be dangerous to use. Please be cautious.*** ---------- This is a 3D scanner that can be built and assembled only with 3D-printed parts, apart from the electronics (full list of components below). The scanner is driven by two stepper-motors and a range-sensor, controlled by a Raspberry PI. All parts have been designed to fit inside a build-volume of 140x140x140mm. # Concept A model is placed in the center of the largest gear (Plate_Gear.stl). One of the stepper-motors will then rotate the object arount it's Z-axis, allowing the range-sensor to measure a relative distance between points on the model. The second stepper-motor will control the range-sensor's vertical position, and thus allowing a scan of the entire hight of the model (limited by the height of the tower). # Assembly See the 3DScanner_assembled.stl for a visual representation. A simple model of the stepper-motors and the distance-sensor has been added to aid in assembly. 1. Place the two stepper-motors in their slots on the base (Base.stl) 2. Connect the body (Body.stl) to the Base, and make sure the stepper-motors fit in their slots 3. Place the small gear (Drive_Gear.stl) in it's slot. It should fit nicely with the shaft of the stepper-motor 4. Place the large gear (Plate_Gear.stl) by tilting it sideways (aligning the teeth with the small gear) 5. Thread the vertical axel (Drive_Shaft.stl) all the way through the rig (Rig.stl) 6. Fit the range-sensof onto the rig (Ref 3DScanner_assembled.stl) 7. Place the tower onto the body 8. Fit the axel onto the shaft of the other stepper-motor. 9. Secure the axel by placing the top on the top of the tower (Tower_Top.stl) Wiring-diagram/-instruction and software-download/-installation will be added when they are ready. # Required components (All parts can be purchased at thepihut.com) * 1x [Raspberry PI 3B+](https://thepihut.com/products/raspberry-pi-3-model-b-plus) * 1x [Adafruit VL53L0X Time of Flight Distance Sensor](https://thepihut.com/products/adafruit-vl53l0x-time-of-flight-distance-sensor-30-to-1000mm) * 1x [Adafruit DC & Stepper Motor HAT](https://thepihut.com/products/adafruit-dc-stepper-motor-hat-for-raspberry-pi-mini-kit) * 2x [Micro Metal Geared Stepper Motor](https://thepihut.com/products/micro-metal-geared-stepper-motor-12v-0-6kg-cm) * Wires, soldering-iron and possibly a [breadboard](https://thepihut.com/collections/prototyping/products/adafruit-full-sized-breadboard) If you have any suggestions for improvement, or other constructive criticism, please leave a comment. --------------------------------------- # Changelog ## 2018-07-29 * Added custom support for threads on Rig.stl to ease printing * Fixed error with Threads on Rig.stl * Halved the clearance for Distance-sensor-taps * Extruded bottom of body.stl for easier printing and more stability * Added Changelog ## 2018-07-25 * Initial Upload
