Multi Ring

thingiverse

This thing was created using Tinkercad. Edit it online at https://www.tinkercad.com/things/8KSi5ZkzZ94. Simple spiked rings; these are size 13-ish, designed for a demo in a kid's 3D printing class. Giving kids rings with spikes on them could have some risks, but it was done anyway. If you plan to use the ring as a defense tool, increase the infill so it becomes essentially solid. 3D-printed objects can be very effective in causing pain; we will upload a series of small devices modeled after basic kubotans and spikes. They are not suitable for long-term use or deployment, but as a cheap, disposable backup option, they're decent.
