Intro Guide
Mercury One Compatibility
E34M1 is compatible with Mercury One.1 without limiting the build area; no print area is lost with stock beds by converting to EVA 3 from a different toolhead. In some configurations, minor adjustments to the Z axis are needed.
An Ender 5 Pro rebuilt as a Mercury One.1 with 330mm rails:
- Has a theoretical build area of 275mm x 275mm;
- Can expect at least 265mm of X axis travel;
- Can expect at least 250mm of Y axis travel (available Y axis depends on the rear intake).
Note
E34M1 is not compatible with Mercury One Classic.

Icons and Terminology
These terms and icons are used throughout the site.
- The icon is used to emphasize that a part is 3D printed.
- The shopping cart icon is for example links. There are no affiliate links on this site.
- Drive: EVA 3 refers to the extruder, stepper, and mount as the Drive module.
- FHCS: flat head cap screw (DIN 7991)
- SHCS: socket head scap screw (DIN 912)
- Voron-style inserts: M3 x 5mm OD x 4mm L heat set inserts
- EVA-style inserts: M3 x 4.6mm OD x 4mm L heat set inserts
Frequently Asked Questions
How does this fit together?
Visit the Tour to get an overview of how the modules are arranged. The Assembly Guide includes videos to assist during your build process.
Is E34M1 supported by ZeroG or EVA?
No, this is a third-party project started by jonspaceharper.
What do I print?
See the Assembly guide's Print Checklist to ensure you have everything.
What print settings should I use?
E34M1 follows the ZeroG Print Settings guidelines.
All STL files are exported in print orientation.
How are Voron-style and EVA-style inserts different?
Voron-style inserts are slightly thicker than EVA inserts. Mercury One relies on Voron-style inserts exclusively, so all E34M1 components use them, as well. Third-party and stock EVA components use EVA-style inserts instead.
Does it matter? Yes: the adjustments we made for the larger, Voron-style inserts make insertion easier and parts fit together better. Users report that it is generally still possible to use Voron-style inserts with parts made for thinner inserts, but post-processing is needed.
Tips
The Modules section contains entries for every component and variant in E34M1. These are labeled with badges, like so:
These badges are meant to speed up reading through many entries at once.
Tap or hover over the icon for an explanation of what each badges means. Some badges use text to provide additional information, such as an contributor's name and profile link.
PTFE Values
22.5
Hotends and drives (extruders) have a PTFE length value, indicated with a badge like the one above. Add the two values to determine how much PTFE tubing you need between your hotend and extruder.
ABL Offsets
8 mm
-15 mm
These badges are references for setting your ABL-to-nozzle offset in firmware. No badge represents an offset of 0.
Compatibility Charts
Standard
A few components are only compatible in specific combinations. This generally relates to whether a part is for a standard-length or UHF-length hotend.
The Hotend Length badge identifies if a component or variant is affected by hotend length.
ABL
The chart below shows which ABL methods are supported by E34M1. Note that the side ABL mount is than EVA 3 stock and that not all ABL methods use them.

Bottom Horns
Most hotends are paired with Standard-length horns. Very long hotends, such as the Rapido UHF, require the UHF bottom horns. The Mosquito has the Trihorns as a cooling workaround.
More about Bottom Horns can be found on the Bottom Horns Modules page.

| E3D Revo Voron | Dual, Kraken |

Cable Management
There are two methods of cable management. The default attachment is the Top module for umbilical users. Third parties offer PCB mounts supporting both umbilical (cable guide) and drag chains.
