3 Way Filament Splitter for Side Spool Mount P1/X1

3-Way Filament Splitter for Bambu Lab with Side Spool Holder Support

Looking for a way to connect multiple filament sources while keeping your setup clean and organized? This 3-way filament splitter is designed for Bambu Lab P1P, P1S, and X1C printers, with a unique twist – one of the inputs is shaped specifically to fit side-mounted spool holders. This makes spool changes faster and easier, especially when the holder is installed on the side of the printer instead of the back.

This splitter was specially designed to work with my side spool holder model, ensuring a perfect fit and optimal tube alignment. You can find that project here: [link]

Key Features:

• Three filament inputs – Connect an AMS, AMS HT or AMS 2 Pro, filament dryer and a spool on a side-mounted holder at the same time for maximum flexibility.
• Side spool holder compatibility – One port is specially shaped to align perfectly with spools mounted on the side of the printer, making filament swaps quick and hassle-free.
• Smart port layout – Two ports face the same direction, and the third is rotated 180°, allowing AMS units to be positioned neatly on the right side of the printer.
• Mounting hole for printer body – Attach directly to the printer frame using the existing structural hole, ideally with a longer screw supplied with the spool holder mounting hardware.
• PTFE 4 mm compatibility – Available in two versions: one for M10 pass-through pneumatic fittings (PC4-M10) and one for M6 pass-through pneumatic fittings (PC4-M6). Choose the correct model in the print profile to match your fittings.
• Clean and efficient routing – Keeps PTFE tubes straight, untangled, and easy to manage, improving both functionality and workspace appearance.

Required Additional Parts

• This splitter requires pass-through pneumatic fittings for 4 mm PTFE tubing. You can use either PC4-M10 or PC4-M6 depending on the selected model. These fittings ensure a secure, leak-free connection for smooth filament feeding.
• Additionally, two M3×10 mm screws are required for mounting. You can buy them or use the screws that come with the printer for attaching the spool holder.

Patch notes:

• The filament splitter model has been updated to allow PTFE tubes to be inserted further inside the device. Using through-type pneumatic fittings is necessary to use this feature. This change helps prevent filament from jamming, reduces friction, and ensures a smoother, more reliable filament flow during printing.
• Updated filament splitter models with a new two-screw mounting design for improved stability.
