The T-Spheres are weapons invented and used by Curtis Holt. The T Spheres are usualy found hovering around Mr. Terrific.
The T-Spheres can perform the following functions:
form a laser grid between the spheres
link to computers/data
be used as a weapon by flying into things
The spheres were originally intended for Felicity Smoak's program for "prototypes for the future" while still working at Palmer Technologies. After Curtis quit the job and joined Team Arrow as Mr. Terrific he continued working on the spheres in order to help him fight crime. Although at first they were not functional, by the time the team encountered Vigilante, he used them successfully to knock him out.
The model is splited in half, and have a cavity allowing you to put lights inside
There are two versions of the model one is splitted in half, and have a cavity allowing you to put lights inside, mimicking the ones on the tv serie arrow.
The other one is just the full sphere.
After printing the model i sand it, apply two coats of primer, sand it again and then paint it using Davincis fet brushes and acrylic paints. Not the best painting job.
