Additional Nut for NutsnBolts Puzzle

Loved the NutsnBolts Puzzle but its asymmetry gnawed at me. So...I edited one piece to make a lone nut to finish the end of the puzzle! Looking forward to sharing this one with my students on "puzzle days"! This is a remix because I didn't know how else to upload the extra stl file. Thank you PArtzzles for the great puzzle!!
