Lantern Corps Rings

Lantern Corps Rings

Summary Green Lanterns have been around for decades, but a recent storyline showed that there was a full spectrum of Lantern Corps, with each pulling their strength from an emotion: Red Lanterns, that get their power from Rage Orange Lanterns, that get their power from Avarice (greed) Yellow Lanterns, that get their power from Fear Green Lanterns, that get their power from Will Blue Lanterns, that get their power from Hope Indigo Lanterns, that get their power from Compassion Violet Lanterns, that get their power from Love In addition, two more lanterns were created based on more abstract concepts: Black Lanterns, that are fueled by death White Lanterns, that are fueled by life. All of the rings are represented in package. I've included the FCSTD files in case you can improve them. Since the original prints, I've tweaked the designs to show up a little better. The rings are sized to a 20mm diameter which fits my adult hands just fine. This can resize upwards just fine (print at 110% to get a band 22MM in diamter, etc). If you want to print smaller, I suggest modifying the internal radius in the FCSTD file first to ensure the back of the ring doesn't get to thin. Good Luck! Print Settings Printer: Monoprice Maker Select Plus Rafts: Yes Supports: Yes Resolution: 0.1mm Infill: 50% Notes: Note that the designs have changed ever so slightly since the rings in the pictures were printed- Specifically Red, Orange, Blue, Indigo, Violet and White were tweaked to print a little better. In addition,I've found its best to print them at a 12 degree angle with the faces tilted slightly up so that the back of the ring and the edge of the face both touch the baseplate. Post-Printing I cheated and printed all 9 at once. For quality's sake, I'd advise against this. Here you can see I had to cut the brims apart. Orange Lantern ring has streamers on it due to printing several next to each other- those are easy enough to shave off. shave shave shave. Use one handed shaving is for demonstration purposes only. since they printed at a 12 degree angle and supports are on, there's a small support behind the face; that can be pulled off with pliers fairly easily. just grab that little support with pliers and work it back and forth until it comes off. more streamers on the back- I probably need to do a bit more tuning. How I Designed This Freecad FTW Design was done completely in FreeCAD 0.1.6 on Linux (Mint KDE 18.1), using various pictures from google as resources. A few of them I dropped into Gimp to measure angles when eyeballing it wasn't getting close enough. After the first printing, I noticed that some of the details were too small to be done at my resolution, so I went back and thickened them up. While I haven't printed them yet, I suspect they'll look much better. Most of the work was done in part design mode, with a bit here and there for fusion and cut in Part mode. First I started with a block for the head. Then I created a blank for the band. These were then merged together using the fusion from the Part Workbench. Next I cut a pocket through to create the inside of the ring. This is the effective size of the ring, which is a 10mm radius, or 20mm diameter. Note that it is slightly offset, allowing the back to be thinner than the front. Next I hollowed out the face- the inner face will be padded out with the actual symbol later. ...and here's the actual symbol. It looks nice, but it still sticks out of the band too far. since it's extruded 2.6 mm, we're going to shave that off with a pocket ring from above. Here the face is properly shaved, but it still needs a few more tweaks. I used the draft tool using the inner face (the inside of the central triangle) as the Neutral plane and the exterior of the head as the face to be adjusted. I tilted it 10 degrees to give it a slight exaggeration. Normally I'd draft the band to make it narrower at the back, but that wasn't playing nice for me, so I created this beast to subtract from the ring itself. and here's the cut version, showing the ring narrowed in the back. And the final step, to fillet the entire inner and outer band by 0.5mm to round it.
