Then please consider to give it a 🚀Boost🚀 and/or ⭐⭐⭐⭐⭐.
I greatly appreciate any kind of support. Thank you very much.

💎 About the Project: 

My aim with this project is to provide mounts for the new Filament Track Switch and TPU Feed Assist Module that are compatible with as many printer setups in the H2 printer series as possible. A combined mount for both modules is available, as well as individual mounts for the Filament Track Switch and the TPU Feed Assist module. Choose the module that best suits your printer setup.

 

 

🚀 Version 2.0 Change log:

• Significantly more compact in depth 
• Adjustable distance to the filament inlets 
• Optimized PTFE tube guidance with minimal friction 
• Optional 4-in-1 adapter mounts (both versions)

 

⚠️ Compatibility Notice:  

• H2C  - Update 01. Jun. 2026 - H2C is now supported.
• H2D - The release of the required firmware version is expected in the second half of 2026.

 

✨ Key Features:

• One combo mount for both modules !!
• Adjustable distance to the filament inlets - Designed to minimize filament friction (New!)
• Optional with 4-in-1 adapter holders  (New!)
• Significantly more compact in depth  (New!)
• Adjustable slider mounts = variable tube length  (New!)
• The external spool holder remains accessible! 
• Easy assembly: No additional hardware needed – all required parts are included with the original kits.

🔭  Outlook

I am constantly improving the collection and adding new variants. The following projects are currently in progress: 

• TPU Feed Assist Mounts Version 2.0 in a straight and a 90-degree version
• Filament Track Switch Mounts for setups, with AMS units on the right side of the printer
• Filament Track Switch Mount for PTFE tube feed from below

Do you need a different arrangement or do you have any general suggestions for improvement?

⚙️ Print & Material Recommendations

• Material: 
  • The main body of this mount is exposed to elevated printer chamber temperatures. If printed in standard PLA or basic PETG, the structural bracket may soften and sag under load over time.
  • Main bracket:  ABS, ASA   (heat-resistant material recommended)
  • Slider & 4-in-1 adapters:   PLA, PETG, ABS, ASA (any material works fine)
• Infill: 15%
• Bridging:  Bridge Flow 1.5; Bridge speed reduced to 20 mm/s
• Supports:  Minimal support is required and is already pre-configured in the print profiles. I recommend using PETG as a support interface when printing with PLA (or vice versa) for the cleanest results. It's pre-configured this way in the print profile.
• Slicer Warning:  When slicing, there will apear a warning in terms of floating cantilevers. You can ignore this.

 

🔧 Assembly & Hardware

Installation is straightforward and takes only a few minutes.

• Screws: 2x ST3x12 mm (included with the TPU Feeder Assist) or common M3x12 hex screws.
• Tubing: Adjust the distance to the filament inlets according to your needs and adjust the tube lengths accordingly.
