3D-Scanner V5 open source project

thingiverse

A scanner with the camera moving around the object, instead of turning the object on a table, offers several advantages in photogrammetry, resulting in a more realistic 3D image. The scanner is foldable and quick to set up, making it easy to use. All parts are easy to print, requiring a minimum printer surface area of 20 x 20 cm. The best results can be achieved with PETG or ABS materials, using at least four layers and ten percent infill. Additional material needed for the scanner includes aluminum or carbon tubes with an outer diameter of eight millimeters. Two pieces of tubing are required, each measuring 420 millimeters in length. Another two pieces of tubing, also with an outer diameter of eight millimeters but measuring 460 millimeters in length, are needed as well. Some bolts and nuts of various sizes, including four-millimeter, five-millimeter, and six-millimeter bolts, are required. An eight-millimeter threaded rod approximately 250 millimeters long is also necessary. A few cable ties will be needed to secure the tubing in place. For the controller, a Raspberry Pi with Python programming language is used. Four relays rated for five volts each are required, as well as a power bank with at least ten ampere-hours capacity to power the Raspberry Pi. A six-volt battery is needed to power the gearmotors. Two geared motors, each measuring 120 revolutions per minute and 25 millimeters in diameter, are necessary. These can be obtained from various online retailers, such as Amazon. For triggering the camera, a few options are available. Two additional relays can be connected to a "tapped" cable release to trigger the camera. Alternatively, a mini servo can be attached to the camera release using an adapter, allowing for mechanical triggering of the camera. Another option is to connect to the existing WLAN connection of the camera, if it has one. For more advanced users, electronics with Arduino can be used for control. A control board with Arduino is available for purchase online from various retailers. This is a trial version and may still undergo changes.
