- The shopping cart icon indicates an external link to a shopping website.
- These links are not an endorsement and for reference only.
- The design allows for longer-than-specified screws in certain locations. The assembly guide notes where substitutions can be made.
- Wiring is only specified for the IEC power socket, power switch, and power supply. Additional wiring and fusing considerations are configuration-specific.
Universal Bill of Materials
These parts are common to all case builds. See below for additional requirements based on configuration.
| Item | Qty | UOM | Note |

| Fork connectors, 14-16 awg, #8, Insulated | 1 | ea | Ring connectors can be used as well. |
| SPST snap-in rocker switch | 1 | ea | 30mm x 11mm profile. Identical to Creality Ender power switch. |
| IEC C14 socket with fuse | 1 | ea | |
| Glass Fuse, 5x20mm | 1 | ea | See note below. |
| Compatible MCU | 1 | ea | See the Supported Parts list. |
| Compatible 128x64 or TFT LCD display | 1 | ea | See the Supported Parts list. |
| Compatible power supply | 1 | ea | See the Supported Parts list. |
Note: Glass Fuses
Socket fuses do not replace the fuses on your board or inline fuses.
Users will typically want to fuse with fast or medium blow fuses on the socket. Determining the correct fuse for a given configuration is beyond the scope of this documentation. The Oznium blog has an excellent guide on choosing a fuse size.
Note: Wiring and Connectors
This list is not all-encompassing for wiring. Additional connectors and wiring may be needed, including for grounding your bed/frame to earth.
Fasteners
Cases with heat set inserts use shorter fasteners in some locations. Use the Stock list if you are not printing a case with inserts.
OmniBox is compatible with both socket head and button head cap screws. All links are to socket head screws, where applicable.
| Fasteners | Qty | UOM | Note |
|---|---|---|---|
| M3 x 6mm machine screws | 4 | ea | |
| M3 x 8mm machine screws | 44 | ea | |
| M3 x 10mm machine screws | 6 | ea | May use 12mm instead to simplify materials. |
| M3 x 12mm machine screws | 8 | ea | |
| M3 x 20mm machine screws | 2 | ea | |
| #6 x 3/4" sharp point wood screws | 8 | ea | See note below. |
| Fasteners | Qty | UOM | Note |
|---|---|---|---|
| Heat Set Insert, M3, 4.6mm OD | 24 | ea | Tested with both 4mm and 5.7mm length. |
| M3 x 6mm machine screws | 24 | ea | |
| M3 x 8mm machine screws | 28 | ea | |
| M3 x 10mm machine screws | 2 | ea | May use 12mm instead to simplify materials. |
| M3 x 12mm machine screws | 8 | ea | |
| M3 x 20mm machine screws | 2 | ea | |
| #6 x 3/4" sharp point wood screws | 8 | ea | See note below. |
Additionally, you will need an M3 soldering iron tip for heat set inserts.
Note: Sharp Point Wood Screws
To substitute #6 x 3/4" with Metric screws, use M3 x 16mm or M3 x 20mm. Equivalent length machine screws can also be used if sharp point screws are unavailable.
Heat Set Inserts
M3 x 4.6mm outer diameter inserts will be replaced in future releases with the more common "Voron-style" inserts that are M3 x 5mm outer diameter and 4mm in length.
User mods that require inserts universally use the Voron-style inserts.
MicroSD Reader Extensions
Each MCU tray entry has a field for whether a short or long MicroSD card reader extension is necessary (if using one for the front panel).
Core Configurations with Fans
Most Core component configurations mount at least one fan. The materials necessary are specified below.
Base - Front
The base can mount up to three concealed 40mm fans in the intakes. The following are needed to mount each fan:
| Item | Qty | UOM | Note |
|---|---|---|---|
| 40x40x10mm axial fan | 1 | ea | |
| M3 x 16mm machine screws | 4 | ea | Some fans have recesses that instead use 10-12mm screws. |
Main Body - Front
There are two versions of the front main body.
This version of the front main body has an optional 40mm fan.
| Item | Qty | UOM | Note |
|---|---|---|---|
| 40x40x10mm axial fan | 1 | ea | |
| M3 x 16mm machine screws | 4 | ea | Some fans have recesses that instead use 10-12mm screws. |
This version of the front main body requires an externally mounted 60mm fan.
| Item | Qty | UOM | Note |
|---|---|---|---|
| 60x60x15mm axial fan | 1 | ea | May also use 20mm or 25mm thick fans. |
| M4 x 25mm machine screws | 4 | ea | Add 10mm to fan depth for thicker fans. |
| Fan Cage | 1 | ea | Printed. |
| Fan Gasket | 1 | ea | Printed TPU. Optional. |
Main Body - Rear
The rear body also has two versions: one with dual exhausts and one without any.
This version adds two (2) externally mounted 40mm fans.
| Item | Qty | UOM | Note |
|---|---|---|---|
| 40x40x10mm axial fans | 2 | ea | |
| M3 x 20mm machine screws | 8 | ea | Use 30mm screws for 20mm fans (not recommended). |
| Fan Cage | 2 | ea | Printed. |
| Fan Gasket | 2 | ea | Printed TPU. Optional. |
There are no additional materials required for this version.
Important
This rear main body must be used with a rear panel or lid that provides an exhaust fan.
Tray and Panel Configurations
The Universal Bill of Materials includes the fasteners needed to mount panels and the the required trays. It does not include the hardware needed to attach anything to those panels and trays.
The Supported Parts Overview has a full list of parts and mounting locations. Some configurations require additional fasteners or fans.
PSU Trays
Power supplies are notable for mounting to the tray with M4 x 6mm screws. See the list of supported PSUs for quantities.
Lower Bay Trays
Each tray (short or long) uses four (4) M3 x 6mm screws to mount the tray. Additional materials are listed on the Lower Bay Components page.
Panel Mounted Parts
Panel mounts are a way of providing external connectors to internal parts, such as the MCU or CPU board USB ports. The Panel Mounts page discusses this in more detail.
