Action Figure Base Stand Clear
Got two of these from Sirtoys and I didn't know these are for Gundam figures.
They come with a 3mm port that fits in most figures although it's a bit lose and once plugged the figures rotate so I added a bit of nail polish to it.
A caveat is that the base is very big because it needs to support the extra arm, but the good side is that because of the extra support it doesn't bend down from holding a figure for a long time.
