Support Overview
OmniBox has a large number of available components, many with multiple variants. Some of these have several printed pieces. Simply:
- A component is a common design, such as an MCU tray for a Bigtreetech SKR E3.
- A variant is a modified version of a component, such as a version of the above tray that takes heat set inserts.
- For simplicity, components and variants are called parts.
Each part has an entry containing a bill of materials and other important information. Some parts have more than one printed piece; the BOM lists all printed pieces necessary and a download link.
The layout of this documentation is standardized, and most sections are organized by the name of the electronic component a part is designed to mount.
Below are explanations of the information you'll find in each part entry.
Fit Testing
Before a part is merged into the main branch, it has to be tested. Parts
that are waiting for fit testing are marked like this:
Fit Test Pending: Issue #NNN
"#NNN" is a link to the open fit test issue on GitHub. If you print a part waiting for fit testing, please report your results!
Badges
Icon badges provide many details about a part at a glance.
Basics
Size
Short
Long
Indicates the size of a part; this applies to lower bay trays and lids. Two (2) Short parts replace one (1) Long part.
Unified
Unified
Indicates a part is a single piece that replaces front and rear halves. Unified parts require large build plates.
Front and Rear
Front
Rear
Front and Rear parts can be printed in place of a Unified part. Unlike Short parts, Front and Rear parts are not interchangeable. This badge applies to Bases, Main Bodies, and Bottom Panels.
Heat Set Insert
Indicates a part requires heat set inserts.

Versioning
Template
template_version
All parts are based upon templates. These are useful in determining compatibility between parts and Core versions. See the Templates page for more.
Version
part_version
The current revision of a part, if applicable.
Bases and PSUs
Switch
Rocker
Toggle
None
Identifies the type of power switch(es) compatible with a given power supply or base.
Depth
36mm
42mm
For a base, this is the available depth for mounting a power supply. For a PSU, indicates the depth required.
IEC C14
These badges indicate if a Base mounts an IEC C14 power inlet.
Panel-specific
Display
CPU
MCU
Indicates whether a display panel mounts a display that connects to a CPU or MCU.
Fan, Vent
Fan badges indicate that a part has a fan mount; vent badges signal that a part has cutouts for airflow.
Panel Mount
USB C, RJ-45
These badges list the types of panel mounts available on a given part.
Support Sections
General
| Topic | Description |
|---|---|
| Panel Mounts | Supported types of panel-mounted connectors. |
| Fans | Types of fans with internal or external mounts. |
Core
| Component | Description |
|---|---|
| Base | Mounts the power supply and bottom panel(s); acts as a foundation for the Main Body. |
| Main Body | Mounts most trays and panels; serves as the heart of the case. |
Trays
| Tray Type | Description |
|---|---|
| MCU Trays | MCUs are mounted directly underneath the lid for easy access. |
| CPU Trays | Trays with an integrated panel; can slide out from the side of the case. |
| PSU Trays | Power supplies are inserted from below as part of the Base. |
| Lower Bay Trays | Mount other miscellaneous parts (e.g., solid state relays, buck converters). |
Panels
| Panel Type | Description |
|---|---|
| Display Panels | Mount LCD and TFT displays. |
| Bottom Panels | Protect the PSU and allow airflow, if needed. |
| Front Panels | User-facing panel for small ports and lights. |
| Lids | Serve many purposes, including mounting large fans and/or a handle. |
| Rear Panels | Pass-through wiring to your printer and can mount medium-sized fans. |
| Side Panels | Act as air inlets and connector panels. |
