Laboratory Badge Charm

I made these badge reels to hot glue onto any standard bulk badge reels you can get on Amazon. I used a 0.4 nozzle for these, however they would look better with a 0.2 or slightly scaled up since the text has a hard time printing correctly. I also suggest using 100 percent infill to prevent coloring from the text bleeding through on any light colored backgrounds or the infill from showing through. They're between 4-6 mm thick so solid infill would help prevent breakage during heavy use.
