V3 Filament Track Switch & TPU Feed Assist Mounts

Boost Me Enjoying the Mount? Then please consider to give it a 🚀Boost🚀 and/or ⭐⭐⭐⭐⭐. I greatly appreciate any kind of support. Thank you very much. ⚠️ Which mount to choose?

You can choose from two versions, depending on your setup:

V3 Compact Mount   (this model)

V4 Low Friction Mount

- Extremely slim and compact design. - Still offers a very direct filament path.

👉 Choose this model if the space behind the printer is limited.

- Straightest possible filament path with minimal resistance. - Requires more space behind the printer as cables protrude at the front and rear. 👉 Choose this model if there's enough space behind the printer

🚀 Version 3.0 Change log:

- More Compact Design: Smaller footprint and space-saving overall geometry. - Warp-Resistant (PETG Ready): Compared to V2 significantly reduced contact surface against the heated rear printer panel. Safe to print in PETG without deforming when chamber heating is active. - Improved TPU Tube Routing: Lowered the TPU module position for a straighter filament path and improved compatibility with custom riser systems.

✨ Key Features:

- All-in-One Combo Mount:   Holds both the Filament Track Switch and TPU Feed Assist modules on a single bracket. - Low Friction Design:   Adjustable distance to the filament inlets to minimize filament friction. - Two TPU Placement Options:   Choose between Classic Straight or 90° Rotated. - Integrated 4-in-1 Adapter Holders:   Compatible with both older classic and newer H2C 4-in-1 adapters. - Full Spool Access:   The external spool holder remains accessible. - Easy Assembly:   Just two screws required.

📦 Print Profiles

The print profiles are fully preconfigured and include both variants:

- Classic Straight Alignment (TPU Feed Assist arranged in a straight line) - 90° Rotated Alignment (TPU Feed Assist rotated sideways) Please use the preconfigured print profiles, as many parameters have been optimized to ensure a clean print result.

Print profiles are available for both PETG and ABS.

Included Components:

- Main Combo Bracket - Track Switch Sliders (with or without 4-in-1 adapter holder) - 4-in-1 Adapter Holders (variants for classic or H2C 4-in-1 adapters) - Magnetic PTFE Connector Holders (for 6x3 mm or 10x5x3 mm magnets – ideal for positioning the tube directly in front of the inlet) - Dummy PTFE Connector for 90° rotated version (for clean tube management) 💡Note on Parts:

All modular options are included on the plates. You don't need to print everything!

Simply select the parts you need and delete the rest before printing.

⚙️ Print & Material Recommendations

- Material: - PETG is recommended , ABS and ASA are fine too. - Please do NOT print the main bracket in PLA. When chamber heating is enabled, the rear printer panel heats up to 55 °C / 131 °F , which is too hot for PLA.  Only p arts that do not come into contact with the back can be printed in PLA - Print Settings: - Nozzle: 0.4 mm - Layer Height: 0.2 mm - Supports: Minimal supports required (pre-configured in the profiles). - Pro Tip: For the PETG profile, I highly recommend printing with a PLA support interface for effortless support removal. This is already pre-set in the PETG profile. 🔧 Assembly & Hardware

- Upper Mounting Hole: 1x BT3x12 mm self-tapping screw - Lower Mounting Hole: 1x ST3x12 mm screw (included with the TPU Feed Assist) OR standard M3x12 mm hex screw - For the 90° Rotated TPU Variant: 2x additional M3x12 mm screws (self-tapping or hex screws)
