About this 3D model

# CM3D-MMU3-10C ## About the 10 colors MMU This project has been inspired by the work of the @Ryper3D in fact many of their parts has been used on this project because of that I would like to give to them the Kudos that they deserve. If you want to know about their work please visit their printables profile ## AIMS of this project The aim of this project is to deliver the posibility to use up to 10 different colors on a printer without spend too much money on the way to achive it. If you already own an MMU2/3 unit you will have to spend less than 65€ ## BOM [!IMPORTANT] Is necessary to exchange the Pulley and Idler motor, so the idler motor will be used with for the pulleys in combination of a 5mmx175mm flat shaft and a rigid coupler of 5mm-5mm Item Quantity Link Aprox. price 190mm leadscrew T8 M8 1 5€ 218.5mm smooth rod M5 2 7€ Nema 17 1 11€ 685-2rs bearings 10 6€ 175mm flat shaft M5 1 3dBoom 8€ Rigid coupler 5mm-5mm 1 1.5€ Flex coupler 8mm-5mm 1 1.5€ Shaft 16mm OD5mm 10 4€ GT2 20T Bore 5mm 1 1.5€ ECAS 10 4€ Filament pulley 5 12.3€ SHCS M3x35mm 3 0.3€ ## Assembly guide Basically you will need to follow the assembly guide released by Prusa and apply a little bit of common sense. Is more or less the same ## What about the Firmware? The firmware for the MMU3-10C unit is released on the repository CM3D-Firmware-MMU The firmware for the MK3S+ is released on the repository CM3D-Prusa-Firmware ## How does it works? Well, it just works in the same way than the MMU3 from @prusa3d but with the possibility of use the double of colors.
