Sigmalock First up, these look awesome! Such a simple, yet effective-looking add-on! Nice work ;)
Just to clarify: which material was used in the photo with the Sharpie colouring? White, or White Polished? Or is that actually the Black?
Sigmalock@azmorello Are you able to make these in grey, like your digital preview above (the third one)? Or maybe the grey nylon 'Metallic Plastic', like you have for your Combiner Wars Optimus Prime Smokestacks?
