Had some trouble with the original model printing the helmet visor weird since the external visor is so thin and the model has an internal visor preventing infill from getting to the front of the helmet. Corrected it in blender by removing the internal visor so infill will come all the way forward. Others in the original prints comments seemed to print it fine somehow so this may not of been necessary, but ill upload anyway just in case someone else had this problem.
The author remixed this model.
Internal visor of original model removed so it prints better.
