Tested with white processed. Sanding is definitely required on the titans/ head master port, and the 5mm port on the front, especially if painting. 5mm port is snug, and the titan port is abit too small. Will see if I find time to fix it, but for now just keep that in mind if ordering. For myself, I used the Combiner wars gatling gun from an other seller (
ADVENTOYS) for the 5mm chest which I have tested to see if will fit properly. https://www.shapeways.com/product/DV23GV5RU/gatling-gun-for-combiner-wars?optionId=61228322&li=ostatus
