Standoffs

This is a list of the required fasteners with a recommended, reliable manufacturer. These parts are standardized, however, and can often be bought cheaper in bulk or sets.

Manufacturer Item Description Avg MSRP Unit Cost Qty. Avg Total Cost
Harwin M2.5-8mm+4mm Standoff This standoff can be used in place of the M2.5-12mm+3mm standoffs that come with the Raspberry Pi official 7" display for mounting the Raspberry Pi. This decreases the profile of the display, allowing easier access to the USB ports through the kiosk maintenance panel. $1.15 4 $4.60
Harwin M2.5-15mm+4mm Standoff This standoff can be used in place of the M2.5-12mm+3mm standoffs that come with the Raspberry Pi official 7" display for mounting the Raspberry Pi.

Electronics

Computer

For an individual POP Kiosk, you only need to buy one of the computers below. The Model 4B is the latest generation Raspberry Pi microcomputer and is recommended for most applications requiring video or 3D rendering. The Model 3B+ is the previous generation Raspberry Pi microcomputer and will work in some applications.

Manufacturer Part Description Avg MSRP Unit Cost Qty. Avg Total Cost
Raspberry Pi Model 4B (1GB) This is the primary computer system that will power the POP kiosk. $35.00 1 $35.00
Model 3B+ (1GB) This is the primary computer system that will power the POP kiosk. $35.00 1 $35.00

Touchscreen Display

This part will act as both the display for the kiosk, as well as the only input device. The Raspberry Pi Official 7" touchscreen is the only display compatible with the POP kiosk case.

Manufacturer Part Description Avg MSRP Unit Cost Qty. Total Cost
Raspberry Pi Official 7" Touchscreen This is the primary touchscreen display used for the POP 7" kiosk. $75.00 1 $75.00

Storage

This will act as the primary storage for the kiosk and allow it to store data offline.

SanDisk 16GB SD card (Class 10) This SD card should provide enough space for many applications, but it can be increased as needed. $19.95 1 $19.95

Machines

3D Printer

Any Fusion Deposition Modeling (FDM) 3D printer can be used to manufacture the POP kiosk parts, but we recommend these two printers for makers looking to explore 3D printing for the first time. The CR-10 offers a great experience for beginners, while also allowing customization through custom firmware and printer upgrades. The Ender 3 S1 Pro offers slightly less customizability, but it works out-of-the-box with many more advanced filaments.

Manufacturer Part Description Avg MSRP Unit Cost Qty. Total Cost
Creality CR-10 This is a low-cost beginner 3D printer to can be used to learn the basics and expanded to print with advanced materials, such as ASA, PC or PP. $309.00 1 $309.00
Creality Ender-3 S1 Pro This is an entry level 3D printer that can be used to print flexible and more advanced materials out-of-the-box without printer modifications. $479.00 1 $479.00

Consumables

Filament

There is an expansive range of filament materials and colors that can be used to print the POP kiosk case. Many filaments are based on plastics or plastic composites, each of which have their own material characteristics and environmental concerns.

For prototyping and non-production uses, we recommend using PLA (polylactic acid) because it is low-cost while still offering high print speed and quality. For final production prints, we use PETG for gallery kiosks. We chose PC or PP for cases that are subject to bumps and abrasion through travel and storage. TPU or TPE are used for parts that require flexibility.

Manufacturer Part Material Description Avg MSRP Unit Cost Qty. Total Cost
Amazon Basics PLA PLA (Polylactic Acid) This is a reasonably-priced, moderate-quality filament that can be used to rapidly prototype and trial kiosk parts. This material is brittle with low impact resistance.


PLA is not commercially recyclable and only biodegradable under specific conditions.

$22.00 1 $22.00
Overture Eco PLA PLA (Polylactic Acid) This is a reasonably-priced, moderate-quality filament that can be used to rapidly prototype and trial kiosk parts. This material is brittle with low impact resistance. This filament is partially created with manufacturer PLA scraps to decrease waste.


PLA is not commercially recyclable and only biodegradable under specific conditions.

$18.00 1 $18.00
Overture PLA Professional PLA (Polylactic Acid) This is a reasonably-priced, high-quality filament that can be used to print kiosk parts for interactive kiosk evaluations. It has decent durability characteristics, but is still not recommended for production use.


PLA is not commercially recyclable and only biodegradable under specific conditions.

$25.00 1 $25.00
Overture PETG PETG (Polyethylene terephthalate glycol) This is a reasonably-priced, high-quality filament that can be used to print kiosk parts for use in a low-traffic gallery. PETG offers good impact resistance, but has poor abrasion resistance and it is not recommended for travelling applications.


PETG is slightly more difficult to print than PLA. It is not recyclable or biodegradable.

$19.99 1 $19.99
Terrafillum PLA/PP Blend Composite PLA (Polylactic Acid) and PP (Polypropylene) This is an expensive and high-quality filament that can be used to print final production kiosk parts for high-traffic applications. The PP in this blend allows for more flexibility and durability than traditionally brittle PLA.


This is an advanced material that requires extensive hands-on experience with 3D printing. This material is neither recyclable nor degradable, but its creation generally has a lower environmental impact than most other materials.

$57.00 1 $57.00
Polymaker PolyMax PC PC (Polycarbonate) This is an expensive and high-quality filament that can be used to print final production kiosk parts for high-traffic applications. Polycarbonate can slightly flex without warping or discoloring. It is impact and temperature resistant.


This is an advanced material that requires extensive hands-on experience with 3D printing. This material is not degradable, but it is infinitely recyclable without loss to mechanical properties.

$48.30 1 $48.30
NinjaTek Chinchilla TPE (Thermoplastic Elastomer) This is an expensive and high-quality filament that can be used to print the final production bumper for high-traffic applications. It is soft to the touch and flexible. This material is chemical-resistant, oil-resistant and tested to be skin-safe.


This is an advanced material that requires extensive hands-on experience with 3D printing. This material may require a "direct drive" 3D printer, like the Ender-3 S1 Pro.

$100.94 1 $100.94
NinjaTek NinjaFlex TPU (Thermoplastic Polyurethane) This is an expensive and high-quality filament that can be used to print the final production bumper for travelling applications. This material is firm to the touch and flexible. TPU provides excellent vibration dampening to protect the display during storage.


This is an advanced material that requires extensive hands-on experience with 3D printing. This material may require a "direct drive" 3D printer, like the Ender-3 S1 Pro.

$87.50 1 $87.50
Overture TPU TPU (Thermoplastic Polyurethane) This is a reasonably-priced and high-quality filament that can be used print flexible prototypes or low-traffic applications. When printed with appropriate infill settings, it can provide decent cushioning to the glass display in the event of fall.


This material is more difficult to print than rigid materials. It can be printed with a "bowden" 3D printer, like the CR-10.
