Here's the leader of my CW RID group: Optimus Prime Extra notes: This custom is made from CW Hot Spot, Onslaught, and RID Optimus Prime. I remembered seeing another person's RID Prime custom that had parts that resembled the original figure, but made for CW Hotspot. I tried doing a search on Shapeways, but to no avail. I have theorized that the parts were either from the Kabaya kit, a personal custom, or s KO I don't know about. So I went with Onslaught's chest.
