POP 7 Kiosk Case (part)

This section contains CLIO documentation.

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.

  Case

• 

  Maintenance Port

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. 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.

Features

• Completely self-contained with panel-mounted port for USB-C power.
• Cut-out panel for GPIO access
• Integrated 75x75mm VESA-compliant mount holes.
• Compatible with 3D-printable Modular Mounting System.
• Maintenance port allows for easy access to ethernet and USB ports.
• Integrated 30mm fan port.
• Textured grip for holding the kiosk.
• Optional 5W 8Ω internal speaker

Material

This part is printed with polylactic acid (PLA) or other sturdy plastic, such as Polycarbonate (PC) 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.
