20190130 - After first attempt to print, a failed support ended up causing the entire top to rip from the base, so I have updated the stand into two files, that can be glued together, I think this will help with running the wire as well as you can do that before you glue it. Test print is running now. This should also allow for printing with much less supports.
20190202 - I was really having issues trying to paint the text black, it is so small and even trying with a toothpick I was getting paint on the top, so I made a little stencil that can be put over the ring to help with painting. This is not a required part for the stand, so you only need to print it if you want to.
20190801 - Added a small radius to the post on the stand to make give it a little more strength and it looks better. Updated pictures as well.
So, I recently made this version of the arc reactor: https://www.thingiverse.com/thing:2854850 and it turned out amazing, great work @yonatanorion! I had no plans to use this in cosplay, and wanted it to be more of a decorative peice. And i was not able to find a suitable stand, so i designed this one.
The concept being that you will use a DC PSU and then beable to run a cable through the back of the stand, up the base arm out the back, to the reactor. The hole in the back of the base is measured to fit a female barrel jack.

The bezel is seperate so it can be printed flat to not skew the text (I have included the svg file if you want to play with the size of this in Fusion360). there is a small ridge that it can easily be glued to after its complete.
If you are going to cover with glass/plexiglass, you will need to notch the back to fit the tube for the cable.
I have included the Fusion360 files, the Text SVG, the STLs, pics, and a few STL files from the orginal reactor project i used to model around, so feel free to modify. I pieced the Reactor together in 3DBuilder, so it probably not accurate enough to be used for anything else. (Just and FYI, I just needed some shapes to model off).
