POP 7 Kiosk Case (part)
Overview
This is the main case that protects the Raspberry Pi computer and touchscreen display. It attaches directly to the four screw holes on the Raspberry Pi official display using M3 screws.
POP Kiosk 7" case
POP Kiosk 7" maintenance panel
This case has an integrated 75x75mm VESA-compliant M4 mount holes. It can also be used with a 3D-printed mount attachment that can attach to the back, top or bottom side of the case. This attachment is compatible with the popular Modular Mounting System[1]. We include a C-clamp, durable foot and 3D printer frame attachment. There is a maintenance port that allows access to the USB and ethernet ports. There are holes for panel mounting a USB-C slot to reduce wear on the Raspberry Pi itself. There is an optional 30mm fan to keep the kiosk cool during operation, as well as plenty of air vents. There is a cut-out panel for GPIO port access to control external hardware. The GPIO can also be used to add a 5W 8Ω internal speaker to the kiosk.

Material
This part is printed with polylactic acid (PLA) or other sturdy plastic, such as Polypropylene (PP) or Acrylonitrile styrene acrylate (ASA).
Printing This Part
Slicing
Orientation
| Part | Notes | Example |
|---|---|---|
| Kiosk Case | We recommend printing the case with the screen bezel adhering to the print plate.
This will require the use of more supports, but will result in a better overall print result. |
|
| Maintenance Panel | We recommend printing the maintenance panel with the front facing up.
This will require supports, but will result in a better overall print result. |

Settings
Kiosk Case
We start with the default "Standard Quality" 0.2 mm print profile. We recommend the following settings overrides:
| Setting | Recommendation | Notes |
|---|---|---|
| Shell - Wall Line Count | 4 | This was increased from the default to increase the durability when higher amounts of stress are applied. |
| Shell - Bottom Layers | 4 | This provides a good mixture of durability and material conservation. |
| Shell - Top Layers | 4 | This provides a solid top layer that is symmetrical with our bottom layer. |
| Infill - Density | 50% | This part is a hollow shell and does not have many gaps between the walls that require infill. Nevertheless, this is set higher than normal to improve impact resistance at the curved corners. |
| Infill - Pattern | Tri-Hexagon
Cubic Subdivision |
These infill patterns provide good internal support in multiple directions. Tri-Hexagon uses less filament but is also less durable. |
| Speed - Print Speed | 40mm/s | For final production prints, we recommend printing slower than average to decrease stringing with small holes. |
| Support - Generate Support | Yes | This part has a lot of overhangs that require the use of supports. |
| Support - Support Structure | Tree | We highly recommend tree supports instead of normal supports. They take more time, but they require less filament and are much easier to remove from inside the case. |
| Support - Support Placement | Touching Buildplate | Only printing supports that touch the build plate are much easier to remove from this print. |
| Build Plate Adhesion - Adhesion Type | Skirt | This part has a lot of contact with the print bed and should not require a raft. |
| Experimental - Small Hole Max Size | 30mm | This will cause the printer to print slower when it is printing the nut and bolt holes on the back of the case. |
Maintenance Panel
We start with the default "Standard Quality" 0.2 mm print profile. We recommend the following settings overrides:
| Setting | Recommendation | Notes |
|---|---|---|
| Shell - Wall Line Count | 4 | This was increased from the default to increase the durability when higher amounts of stress are applied. |
| Shell - Bottom Layers | 3 | This provides a good mixture of durability and material conservation. |
| Shell - Top Layers | 3 | This provides a solid top layer that is symmetrical with our bottom layer. |
| Infill - Density | 15% | This part does not have many gaps between the walls that require infill and is set lower than average. |
| Infill - Pattern | Tri-Hexagon
Cubic Subdivision |
These infill patterns provide good internal support in multiple directions. Tri-Hexagon uses less filament but is also less durable. |
| Speed - Print Speed | 40mm/s | For final production prints, we recommend printing slower than average to decrease stringing with small holes. |
| Support - Generate Support | Yes | This part has a lot of overhangs that require the use of supports. |
| Support - Support Structure | Tree | We highly recommend tree supports instead of normal supports. They take more time, but they require less filament and are much easier to remove from inside the case. |
| Support - Support Placement | Touching Buildplate | Only printing supports that touch the build plate are much easier to remove from this print. |
| Build Plate Adhesion - Adhesion Type | Raft | This part is small and uses a lot of supports, so it is recommended to use a raft. |
Results
Printers
This part has been print tested with the following 3D printers:
| Manufacturer | Model | Notes |
|---|---|---|
| Creality | CR-10 Mini | Excellent print quality. Reliable machine. |
| Creality | CR-10 | Excellent print quality. Reliable machine. |
| Creality | Ender 3 SR-1 Pro |
Build Surface
This part has been print tested with the following build surfaces:
| Method | Notes |
|---|---|
| Painter's tape | |
| Glue stick | Creates an uneven and non-uniform first print layer appearance. |
| Adhesive build surface | First layer may have problems printing full height depending on type and hardness of build surface, but this does not affect the overall printability. |
| Polyetherimide (PEI) build plate | Small parts, like the maintenance panel, will require a raft. |
Filament
This part has been print tested with the following materials:
| Filament | Manufacturer | Notes |
|---|---|---|
| Overture PLA | Overture | Excellent build quality and durability. Good for prototyping or production kiosks. |
| Amazon Basics PLA | Amazon | Decent build quality and durability. Recommended for rapid prototyping. |
