The ONESIE family of cases come in three distinct models; Stealth, Maker and Hats. This will be a guide introducing the ONESIE family, the 3D printable monocoque stealth cases for Raspberry Pi 4 Model B, talk about what makes them different to others on the market, help you determine which would best suit you and act as a file depository.

Overview on the ONESIE Family
So, you’ve finally got your hands on a Raspberry Pi 4 Model B and you want to keep it safe and stylish. A good case will act as a shield from electrostatic forces, improve impact resistance and offer protection from everyday wear and tear for your beautiful credit-card-sized single-board computer. Now you’ve scouted across out over the market and come back uninspired. You want something different, something fresh, something unique, something functional. So, keeping that in mind let me introduce the ONESIE family.
From some of the best minds down in Core Electronics, we present a world’s first to the maker community. The ONESIE is a slide, click down and lock 3D printable case for your own Raspberry Pi 4 Model B. It ensures the same protection as other cases on the market, but it is achieved through a single durable component. This case will keep your Raspberry Pi safe from the dangers of the world and smartly placed slots in combination with feet will ensure the necessary heat dissipation for the Raspberry Pi whilst under operation.
The ONESIE comes in three unique models; Stealth, Maker and Hats. Each case is built for a specific purpose, but the lines and forms share a similar lineage. Perfect for scenarios where multiple Raspberry Pi’s are performing unique tasks, but a consistent aesthetic is desired.
Attached at the bottom of this page are all the print files needed to create any of these models. If you don't have a 3D Printer but really want to be part of the ONESIE revolution, we've got 3D Printing services that you can use to get any of these cases (and anything else you want to be printed) sent directly to you and into your hands.
ONESIE Stealth
Of the ONESIE family, the cleanest and strongest of all the ONESIE cases is undoubtedly the Stealth. Streamlined minimalism whilst retaining functionality was the leading design principle followed. Seen below infographic in an isometric view of the ONESIE Stealth with a Raspberry Pi 4 Model B installed.
Perfect for use as a smart media box. It has easy access to the USB-C Power Supply, both micro HDMI ports, 3.5mm Audio and Composite Output, Micro SD Card, Gigabit Ethernet Plug, all USB2 plugs and USB3 plugs.
It doesn’t allow access to the 40 GIPIO Header Pins, the DSI Display Port or the CSI Camera Connector. This also means it won’t be able to accept HATS (Hardware Attached on Top) such as the Official Raspberry Pi PoE HAT or the Official Raspberry Pi Sense HAT.
Pictures always tell a thousand words so below are digital images of the ONESIE Stealth with a Raspberry Pi 4 Model B installed from all orientations.
ONESIE Maker
The ONESIE Maker is an elegant, functional and strong case with support to the maker community as its main focus. Still offering streamlined minimalism this design allows more cooling for the CPU for overclocking purposes and gives access to all inputs and outputs available on the device. Seen below infographic in an isometric view of the ONESIE Maker with a Raspberry Pi 4 Model B installed.
Perfect for use with a Raspberry Pi 4 Model B used in a maker project or being used for more experimental overclocking purposes. It offers access to the USB-C Power Supply, both micro HDMI ports, 3.5mm Audio and Composite Output, Micro SD Card, Gigabit Ethernet Plug, all USB2 plugs and USB3 plugs, the 40 GPIO Header Pins, the DSI Display port and the CSI Camera Connector. It has a cooling slot placed directly over the 1.5 GHz quad-core Cortex A72 processor, always the hottest part of the board whilst under operation. It also allows a full 40 pin box header to be installed directly onto the GPIO pins.
This model won’t be able to accept HATS (Hardware Attached on Top) such as the Official Raspberry Pi PoE HAT or the Official Raspberry Sense HAT.

ONESIE Hats
The main design focus of ONESIE Hats was to keep the overall aesthetic of the previous ONESIE models whilst retaining strength and allowing compatibility to all HATS (Hardware Attached on Top). HATS are one of the reasons Raspberry Pi have such versatility. This case achieves its design criteria whilst still offering streamlined minimalism. ONESIE Hats protects the installed HATS by an edge barrier whilst still giving access to all inputs and outputs available on the device. Seen below infographic in an isometric view of the ONESIE Hats with a Raspberry Pi 4 Model B installed.
Perfect for use with the Official Raspberry Pi Sense HAT (which allows the device access a plethora of sensors, an interactive LED display and user inputs) or the Official Raspberry Pi PoE HAT (which allows the device to be powered via the Gigabit Ethernet plug). ONESIE Hats cases don't sacrifice strength greatly as compared to other ONESIE cases, allowing for peace of mind in workshop environments. ONESIE Hats cases offer access to the USB-C Power Supply, both micro HDMI ports, 3.5mm Audio and Composite Output, Micro SD Card, Gigabit Ethernet Plug, all USB2 plugs and USB3 plugs, the 40 GPIO Header Pins, the DSI Display port and the CSI Camera Connector. It also allows a full 40 pin box header to be installed directly onto the GPIO pins.
An important word when it comes to installation. Make sure the standoffs are installed in the Raspberry Pi 4 Model B before sliding and click locking it into place. Once the Raspberry Pi 4 Model B is installed into the ONESIE case then place the desired HAT onto the GPIO pins and screw down the HAT into the standoffs.

Installation Process
All ONESIE Cases operate in a similar manner, employing a slide, click down and lock mechanism. This mechanism is best demonstrated via a diagram as you can see below. It is important to make sure the media ports run smoothly through the channel on the left and when the Raspberry Pi 4 Model B is clicked into the final position that the PCB (printed circuit board) is level with the ground and the case is centred on all the input and output ports.
For the ONESIE Hats case, it is important to screw the standoffs into the Raspberry Pi 4 Model B before installation into the case. Then secure and screw the particular HAT into place after the installation into the ONESIE Hats. This is because you won’t be able to access the base screws once the Raspberry Pi is inside the ONESIE Hats case.
For the ONESIE Maker install the Raspberry Pi 4 Model B into the case first if a 40 pin header or any ribbon cables are being used. Also for any other inputs or outputs on the Raspberry Pi 4 Model B only attach cables after the Raspberry Pi has been installed (the Micro SD card, USB2 plugs, USB3 plugs and Gigabit Ethernet ports are the exception to this).
3D Print Settings
All models seen above were printed using ABS on an Ultimaker S5 3D Printer. Ultimaker Cura (which is the open-source 3D printer slicing software created by Ultimaker) was the printing program used and they have been successfully printed in both Normal and Fast Defaults. This is a nozzle size of 0.4mm and Normal print was 0.15mm resolution and Fast was 0.2mm resolution. The printing temperature was 245°C and bed temperature was 85°C. A brim build plate adhesion type was used. Supports were made from ABS, with a support overhang angle of 40° and are required for ONESIE Family of cases. The prints were done with the ONESIE logo facing the sky as you can see below. Depending on your own printer different settings may optimise the print outcome.
