Iron man arc reactor

The initial design came from a file that I found on Thingiverse; however, I am unable to locate the thing in order to give proper recognition. I am posting my make as I would like others to also have the opportunity to create this amazing prop.

If anyone is able to tell me from whom the design is feel free to let me know and the proper recognition will be given.

The files provided caused some problems due to their sizing, however after some experimentation on my part I have determined the scales at which the parts should be printed in order to assemble correctly. The following parts should be scaled by the following factors (I have also indicated the colours in which the parts could be printed):

bp1 (Transparent): x: 104% y: 104% z: 98.11%
bp2 (Silver): x: 103% y: 103% z: 100%
bp3 (Grey): x: 101% y: 101% z: 100%
bp4 (Silver): x: 100% y: 100% z: 100%
bp9 (Silver): x: 98% y: 98% z: 98%

dp1 (Grey): x: 109% y: 106% z: 100%
dp2 (Grey): x: 100% y: 100% z: 100%
dp3 (Grey):
