Multi-Material PTFE Buffer & TPU Assist Mount

Overview

After a significant amount of requests across Reddit, Facebook, and MakerWorld, I am finally making this design public. This is a rugged, highly optimized structural mounting arm engineered to solve multi-material routing headaches by combining a dedicated TPU feeding module and a PTFE hub into a single, seamless, rigid setup.

This design was heavily inspired by the work of raladic. It is engineered specifically to bridge the gap between two excellent community designs, ensuring a flawless path for your filament without friction or snagging.

Compatibility

This module is engineered for a precise fit with the following systems:

• AMS Mount: Fully compatible with the AMS Flipper - better access to your P1S/X1/P2S by Jakob_K_Design.
• TPU Module: Designed to house the TPU Feed Assist - Modern Casing by dedge.

Features

• STEP File Included: The original CAD .step file is provided to ensure maximum dimensional accuracy and to allow for easy community modifications or custom remixes.
• Integrated PTFE Routing: Form-fitting channels to secure your PTFE splitters and hubs precisely, maintaining a natural, smooth bend radius.
• Weight-Optimized Geometry: Strategic cutouts maximize structural rigidity and eliminate sag while minimizing material consumption and print time.

Print Profiles & Slicer Optimization

To make this as plug-and-play as possible, I have uploaded multiple fully optimized print profiles tailored to different environments and hardware configurations:

• Material Variations: Dedicated profiles for ASA, PETG, and PLA, pre-configured for optimal cooling, volumetric flow, and layer adhesion.
• Support Options: Each material variant includes separate profiles configured for standard support material or specialized interface supports, ensuring clean overhang surfaces and easy removal right off the build plate.

Why Boost This Model?

If this integration solved your multi-material routing headaches and cleaned up your workspace, please consider giving it a Boost.

• Community Requested: Released publicly due to popular demand across multiple platforms to help the community achieve cleaner multi-material setups.
• Production Ready Slicing: No need to tweak settings. Optimized profiles for ASA, PETG, and PLA with fine-tuned support configurations are ready to print immediately.
• Open Engineering: Including the STEP file ensures you have complete control over the model data. Your boosts directly support the prototyping time, filament costs, and CAD development for future out-of-the-box hardware modifications.

Solves a Real Problem: No more loose PTFE splitters or awkward TPU assist module placements. It integrates both into a single, clean, rigid structural arm.

Print-Tested Optimization: Fully optimized geometry means zero sag, minimal support usage, and clean clearances for buttons and cables right off the build plate.
