Model

Y-Splitter for the Bambu Lab P1 and X1 Series from suit1337 with text

it is to be used with PC4-M10/MF10 connectors

BOM

• 2 x original screws for PTFE coupler
• 3 x PC4-M10 connectors (Amazon Affiliate Link)

keep in mind most PC4 connectors with “M10” threads actually have M10x1,0 and not M10x1,5 threads, so they are actually MF10 - if you are unsure about your connectors, make a test print of the thread first and see if it fits

Printing

Upright with the “bottom” side of the Y facing downwards

use tree supports only on build plate

print it with minimal layer height - preferably with a somewhat ductile filament, PETG, ABS or ASA works well

Assembly

• Thread the PC4-M10 Connectors in the 3 openings, gently tighten them
• insert some silicone tubes into the connectors and guide a piece of filament (preferably anything hard like PLA or PC) through multiple times to smooth out the fray opening on the side facing the extruder
• remove the silicone tubes and the connectors again and remove any loose debris
• reassemble and install them with the original screws from the original filament guide
