Vòng (ring) đai cho BeeBot (Modification)

I Made this snugfit ring for a beebot. with the Idea that studens and pupils could redesign it to fit their need. 

Does it need not one but serveral sharpie marker holder, design it, attach it and print it

does it need a sword and shield, design it, attach it and print it.

let this be the base for all sorts of attachments for the beebot.
