I'm working on some Green Lantern Cosplay for a party and I needed a big fat ring with the Green Lantern symbol on it. I wasn't quite happy with what I found here and decided to rework a bit of a model I found on Thingiverse. 

I scaled it to fit a ring size 74 (chubby fingers here) and wanted to use a filament change to get the white backdrop. I tried using Tipex on a previous monocolor one but the result wasn't that good. So, I'm ok having a few white layers on the entire ring to get a better final effect. 

The 3MF file should embed all the support how you need it for your Prusa Mini + (but I'll provide ready to use G-Code). 

Printing Settings

• Supports : yes
• Infill: 20%
• Brim: 10mm
• Filament change at 243 and 248 (for the original size)

Take the oath

In brightest day, in blackest night,
No evil shall escape my sight
Let those who worship evil's might,
Beware my power... Green Lantern's light!
