Red_Star_Forge@Dimensioner thank you for the heads up! While it's possible that the mask you received fit improperly due to Shapeways plastic tolerances, we will make sure that our Nuva line has axles that are consistent with our other lines.
Red_Star_Forge@bradshawjosh17 Unfortunately we will not be offering masks that were seen in set form. We want to avoid legal trouble with The Lego Group, and, since others are already doing so, we don't find it necessary to retread explored territory.
Red_Star_Forge@Ralzebun We do our best to ensure that both heads are compatible with our masks. If you have any fitting issues with the Mata head, please let us know. So far we haven't had any issues with our products, though.
