[NOTE:] This was originally published on my Shapeways store, tested using their printers. Tolerances may need to be adjusted.
A chest plate to help convert Power of the Primes Windcharger into the G1 Micromaster and part-time wrestler Roadhandler. I tested this with a print from Shapeways and it does transform successfully. Unfortunately this was also intended to go with another Shapeways user's Roadhandler head, which is now unavailable.
Installation involves removing the pin running through Windcharger's chestplate which will likely crack it(which shouldn't matter since it's being permanently replaced) and removing the screw from the pelvis. From there it's a matter of painting and reinstalling everything.
