Nier Automata Sword Holster Prop

I was wanting to make the floating halo sword holster from Nier Automata so I might be able to do the effect sort of for the floating Cruel Oath on 9s's back in the game for a cosplay of him, its gonna be bolted together with screws and bolts for better strength, I also wanted to attach EngineeringAutomata's pod to my cosplay this: https://www.thingiverse.com/thing:2268272 ,
so i made a little stand I hope might be able to hold onto it......
