Mullet Drivetrain Hack

I remixed the original model with the folowing improvements:
•scale now works without problem
•protruded the nut housing for the screw that holds the pulley to make the whole thing stronger
•added 1mm gap over and under the pulley for two m4 washers that can be glued to the housing to prevent rattling, now it runs smoother and there are no interferences between the screw that holds the cable and the housing
•the screw pinching the cable wasn't reliable enough, so i added a cable guide on the pulley and added the space for a m4 washer (standard, 12mm wide) , that has to be filed on one side to fit in


the model has been printed with the following sizes:
•to make a triple road front shifter work with a mtb triple chainring
shifter: 14mm
derailleur: 21mm

•to make a 9 speed shifter work with a dyna-sis 11 speed derailleur ( m8000 )
shifter: 21.5 mm
derailleur: 35.5 mm
