Green Lantern Ring

thingiverse

Do you have a big sheet of translucent green acrylic laying around and happen to be a big fan of Green Lantern. Well, that's the situation I found myself in, so I decided to make a Green Lantern Ring that can be laser cut. I ended up liking the 3D printed ring better because the translucent green acrylic almost looked yellow in some light making the ring almost look the same color as Sinestro's. The green 3D printer filament looked much better. There are 4 .scad files included. You probably have no use for the ones in inches, because most laser cutters can use millimeters just fine, but I included them just in case. For laser cutting, just download the 2D Green Lantern Ring file and open it up in Open SCAD. Change the ring size and ring thickness to your liking and simply export to a dxf for laser cutting. If you don't have a way to open .scad files, just use Customizer to change the settings and download the .stl files. Then, use a different 3D modeling program to convert the parts to a drawing and export as a .dxf. This model was designed for laser cutting, but it can easily be 3D printed as well. For that either use the scad file of the Green Lantern Ring or Customizer to choose the ring size and other settings. I would highly recommend using a green material to make this out of, but if none is available, feel free to use a different color and some paint. Whatever you do, don't leave the Green Lantern ring any color other than green or it could be confused with a different power ring! :) Print Settings Printer Brand: Ultimaker Printer: Ultimaker 2 Rafts: Doesn't Matter Supports: Yes Resolution: ? Infill: ? Notes: I actually used the Zortrax M200, but they don't provide that option in the print settings drop down menu. A little bit of support material will help the ring to keep the circular shape even at the top. A little bit of sanding might be needed after. How I Designed This I started out designing a ring that would fit me well in SolidWorks. I used variables to control every measurement so it would be relatively easy to make another one for my sister. I slowly realized if I ever wanted to make more than 2 sizes I would have to go back and edit the dimensions again. At this time I had no experience in Open SCAD, but I did have it downloaded. I looked up a tutorial and was amazed. I love programming and I love 3D modeling. Open SCAD is great because I combines them both into the truest form of "object" oriented programming! Looking back, it probably took me way longer to create the .scad file of the ring than it would have to just make all of the common sizes, but learning Open SCAD was a lot of fun and it will make some future projects much easier.
