Iruma-kun Ring of Gluttony/Solomon

Welcome to Demon School! Iruma-kun (jp: 魔入りました! 入間 くん, Hepburn: Mairimashita! Iruma-kun) is one of my favorite ongoing anime and manga series.  As such I wanted to do a cosplay of the titular character. But no one had a convincing Ring of Gluttony available. 

So I made one!

This is a print in place ring that allows one half to spin relative to the other, with very slight bumps at each of the 4 different “modes” 

This ring is a US size 13 which works out great because that's the size of the middle finger on my right hand (where Iruma canonically wears the ring) and also about the absolute smallest you can go while still having the action work correctly. 

Printing Notes:

If you want a ring that rotates, a 0.25 or smaller nozzle is basically required!

Yeah, it sucks, but we're talking clearances that are as small as 0.1mm in some portions, see the in progress pic to see how tight things are. 

I recommend getting some food and skin safe oil/lubricant to help make the action smoother (food grade mineral oil works fairly well, and you only need a couple drops of it)

I used variable layer height so it would not take forever to print, this also played well with the silky filament I used to give it a little more playful shine. I also roccemdn concentric top/bottom infill, and turning ironing on the top layer. The .3mf file provided has these settings already set.
