# 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
