This is the beginning of the low poly human head model. It only prints half so you would need to print one side and then reverse the same model in a slicer so that both half's mirror each other(Only if you desire to print a low poly mask). I'm not sure how to fix this, so if anyone knows what I may be doing wrong or how to fix this, please let me know in the comments.Print the first half of the mask and then mirror the half in a slicer. Print the mirrored half. After each half is printed make sure that the two half's make one mask and mirror each other. Finally glue them together, down the center, using hot glue.
