🚀 ROCKET SPLITTER – 4× Bowden Filament Splitter with Docking Support

The ROCKET SPLITTER is a compact and efficient 4× Bowden tube splitter, designed to minimize filament friction and ensure smooth, reliable filament routing.

Its shape resembles a small missile — hence the name — but the design is driven by function, not aesthetics.

Key Features

• 4-way Bowden splitter optimized for smooth filament flow
• Internal PTFE-guided path: Bowden tubes can be inserted inside the splitter for part of the filament path, drastically reducing contact between filament and printed surfaces
• Inspection window that allows visual verification that all four incoming Bowden tubes are correctly inserted and seated
• Low-friction internal geometry, designed to guide the filament smoothly toward each outlet
• Docking support included (two version), allowing quick attachment and removal of the splitter
• Dual mounting options for the support:
  • Single screw mount

  • Magnetic mount using cylindrical magnets 5×2 mm

Hardware Required

• 5 × PC4-M10 push-fit connectors (through-hole type) (you can easily find on Amazon)
  • 4 input
  • 1 outputs
• PTFE Bowden tubes (standard 4 mm OD)

Why ROCKET SPLITTER?

By letting the filament stay inside PTFE tubing for most of its path, the ROCKET SPLITTER minimizes friction, reduces wear, and improves extrusion consistency, especially in multi-filament or tool-changing setups.

The docking support makes maintenance and filament changes fast and clean — attach it, detach it, done.
