A replacement Matrix-kit for Transformers: Power of the Primes Prime Master figures or Titans Return Titan Master figures. These kits allow for customization of the face while keeping the moving parts and head/body connection from the mass-produced figure for the best fit between head and body.
This item is also available in a sprued set with a pair of g2 Smokescreen guns, here.
This matrix plate is based on Generation 2 Smokescreen. This is also a suitable face for Smokejumper, Beast Wars 2 Starscrem/Starscream, and Smokesniper. To offer maximum value under the current Shapeways structure, this item is being offered as a single face under the 'medium' option, and two sprued faces under the 'large.' For most plastics, there is no cost difference between the two.
This replacement faceplate connector has been tested using Titan Wars Skullsmasher and Blurr, and should be compatible with most Titan Master mini-figures. As prints vary, some sanding/trimming may be required, and some Titan Masters (like Blurr) lack the rectangular connection peg and gluing may be required to fully secure the face.
Some fine details may not show up clearly on prints in strong & flexible plastic.
Use a toothpick or pin to remove any support material inside the connector ports on the back of the face.
Paint and seal as desired. Detail plastic prints will need a light washing with soap and water prior to painting to remove support material residue.
Unscrew the screw in the Titan Master's chest. Remove the original face-plate. Place the new face plate on the figure, replace the screw.
The port does not come pre-threaded, so the initial installation will be tight. If the screw connection is too loose you can secure it with a drop of superglue inside the port prior to reinstalling the screw.
