Sherpa Mini Extruder with PICO MMU Runout filament sensor

You would need to print:

• Shepa Mini Extruder adapter - only one part and swap from the original (5x M3x5x4 inserts needed for the whole mod)
• 4 lane adapter with runout sensor (I've printed one from transparent PET)

Important information:

The MMU 4lane model should be printed horizontally to make the inside layers create a smooth path for the filament.

BOM:

• 2x M3x5x4 insert 
• 2x M3x8 screw

The rest of the necessary parts to run this mod can be found here in the original PICO MMU GitHub repository.

Sherpa Mini Extruder can be found on Annex-Engineering GitHub.
