This front end assumes you are not going to use the MMU2S selector and plan on using a splitter (e.g., Mini Splitter for MMU2+1s mod by Ryper3D | Download free STL model | PrusaPrinters ). I used the original front end (mmu2-front-PTFE-holder) and added Prusa MMU2 PTFE Holder M10 Passthrough Adapter with fillet by ckovacs - Thingiverse using Tinkercad.
You will need 5 PC4-M10 passthrough fittings. I have used these on multiple occasions Amazon.com: Witbot PC4-M10 Male Straight Pneumatic PTFE Tube Push In Quick Fitting Connector for E3D-V6 Long-Distance Bowden Extruder 3D Printer (Pack of 10pcs) : Industrial & Scientific. The front PTFE holder is attached to the pulley body with 4 M3x10 screws.
