Printing the POP Kiosk Case
Process
Install a Slicing Program
Ultimaker Cura is an open-source application that takes 3D models and turn them into GCODE instructions for a 3D printer.
Slice the Print Job
We will need to use Ultimate Cura to create GCODE for each kiosk part we need to print. You can slice the parts all at once, or one-by-one as you need to print them. It's entirely up to you. We provide basic setting recommendations for each part below.
Prepare the Print Surface
Depending on 3D printer model or the print surface you use, this can look different. There are print beds that work best with glue or tape, while others use tacky hairspray. There are also print surfaces that don't require any surface treatment prior to printing.
Start the Print Job
Getting a print job started can happen in different ways and may require different steps, but the desired result is always the same: a successful print.
Finish the Print Job
After the printer has completed, we still need to remove any support structures from the print. Optionally, we can finish the part we just made by sanding, priming and painting it.
Parts
Case
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. 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.
Protection
Collar
The collar protects the exposed edges of the Raspberry Pi touchscreen display, decreasing the chances that the kiosk screen will be damaged from minor bumps and falls. It is printed in two parts and held together by M2 screws.
Bumper
The bumper also protects the exposed edges of display, but it is printed as one part with a soft and flexible TPU filament. When printed with specific infill settings, it can provide additional protection to bumps and falls. This bumper is used instead of the collar and was created for use in mobile pop-up exhibits.
Cover
The cover provides protection to the front of the kiosk display by attaching directly to the collar or bumper. This cover was created to provide protection to the glass screen during transport and storage.
Mount
Modular Case Adapter
This adapter is attached to the back, top or bottom of the kiosk using two M5 bolts. It can be used with any accessories created for the popular Modular Mounting System[2]. It is printed in two parts and attached together with an M5 bolt and optional glue. The mount can be used with a two- or three-prong adapter.
Arm
There are 30mm, 60mm, 90mm 150mm and 240mm arm attachments for the Modular Mounting System. These can be used to extend the length of the mount system, but caution should be used to verify that the kiosk is fully supported. This includes axis changers and prong adapters.
Foot
The foot is used to display the kiosk on a flat surface, such as a table or shelf. It is printed in two parts then attached together with an M5 bolt and optional glue. The foot can be used with a two- or three-prong adapter. The foot can be used with suction cups to more securely attach to sheer surfaces, such as glass or polished stone. Additionally, 3D printed TPU or third-party anti-slip grips can be attached to the bottom.
Clamp
The clamp can be used to attach the kiosk to tables, desks or similar ledges.
Thumbscrews
The thumbscrews are used with standard M5 bolts to make it easier to tighten and loosen accessories.
Accessories
Camera
The Official Raspberry Pi camera can be attached to the case using the Modular Mounting system.
