Dual E3D V6 Hotend 3D Printing STL Models

This collection gathers STL files for adapting and switching dual E3D V6 hotends on common 3D printer frames. You will find mounts, fan ducts, covers and small organizer boxes that complete the hotend setup. It is useful when you need a starting point for a dual-hotend conversion or want to compare mounting approaches. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

How this collection is put together

Polyzon assembles this collection from search results on the connected platforms. Repeats and models without a preview are removed, weak matches go to the end, and the rest keeps the search order. Models belong to their authors — check the terms on each model's page.

About the category

«Dual E3D V6 Hotend 3D Printing STL Models»

Mounts and carriages position two hotends on an X-axis assembly, while Y mergers and splitters join two filament paths before the hotend. Fan ducts and covers differ by airflow path, mounting pattern and whether they enclose the heater block. Nozzle boxes and storage trays serve organization rather than extrusion, so they follow different design priorities.

Before printing, check the model page for the stated carriage spacing, hotend spacing and fan size, since these determine whether the parts match an existing motion system. Look at the number of printed parts, the screws and inserts the author lists, and whether the duct requires supports. Photos of installed prints help judge clearance around the heater block and cable routing.

To narrow results, combine the hotend name with terms such as mount, carriage, fan duct, cover, Y splitter or Bowden merger. Related searches include dual extrusion, tool changer, hotend holder, part cooling and cable chain. If a specific frame is not represented, try broader phrases like dual hotend adapter or switching hotend plate.

FAQ

Frequently asked questions

What is the difference between a dual hotend mount and a Y merger?
A dual hotend mount holds two hotends on the carriage and sets their spacing. A Y merger joins two filament paths into one hotend, so it solves a different part of the setup.
How can I check whether a dual E3D V6 mount fits an existing printer?
Compare the carriage mounting pattern, hotend spacing and fan size listed on the model page with the measurements of the printer. The author's photos and part list often show the required screws and inserts.
Do dual hotend fan ducts need two fans?
Some ducts use one fan to cool both hotends, while others are designed around two or three fans. The model page should state the fan count, airflow direction and whether the duct covers the heater blocks.
What should be checked before printing hotend covers or boxes?
Check the internal dimensions, wall thickness and mounting points against the hotend and the intended location. For storage boxes, confirm that the lid and latch geometry match the printed parts.
