One of the core benefits of open hardware design for scientific equipment is to build easily on other people's work by making modest changes to provide customized functionality for your own lab. To obtain some practice for this skill this project involves customizing an existing scientific tool.
Your project: develop an OpenSCAD script to make a 3-D printable model of your randomly selected crystal structure: Due Date Oct 4, 2017
Assignment
- Register with a free account at https://www.youmagine.com/
- Choose an existing design by looking through examples here or search for specific tools in existing repositories
- Using Blender or OpenSCAD or FreeCAD or combination of them customize in some way the tool you are interested in
- Print your design with appropriate infill for item.
- Upload new design to Youmagine (STL,source and photograph) with a brief description of how you did it with sources. Make sure to give credit to the original designer and follow the appropriate open source license.
- In Appropedia gallery below add your image and hyperlink to your design on Youmagine
- Bring printed design to class on 10/18 – put your name on the paper slip and the class you are in and tape it to your design so that it will not come off!
Steps
- Get random structure from class, check on past attempts http://www.yeggi.com/
- Look it up- lay out geometry
- Make parametric SCAD model with OpenSCAD
- Differentiate atoms in some way (e.g. color)
- Select part and wire model (e.g. straws, stir sticks, etc.) or print solid with fasteners (e.g. snap fit)
- Ensure reasonably flat base
- Realistic sizing- e.g. use scaling – make sure atoms are appropriately scaled to one another
- At least 1 unit cell
- Register with a free account at NIH 3D Print Exchange https://3dprint.nih.gov/
- Post SCAD and STL at NIH 3D Print Exchange https://3dprint.nih.gov/
- Print Full Color Model at FabLab on FFF 3-D printers and bring to class (Tape your name-write your name on it)
- Add a photo of your print with a link to your models in the gallery on the Appropedia assignment page
