V4 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

V4  (this model) 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 4.0 Change log:

- Straight and direct Filament Path: The Track Switch is rotated by 90 degrees, lying flat and aligned inline with the filament inlets. - 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:

Both print profiles include pre-sliced plates for PETG and ABS. 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 - Slider holder:  2x additional M3x12 mm screws (self-tapping or hex screws)
