Raspberry Pi 5 Wall Kiosk with Barcode Scanner

I made this case for the kiosk of my pantry app, Estoki: a screen on the storage-room wall where you hold a pack up to the window under the screen and it reads the barcode. The case works for any Pi 5 project that wants a touch screen and a scanner on a wall.

What it holds: a Raspberry Pi 5 (with an optional PoE HAT), the Raspberry Pi Touch Display 2 in landscape, and the Waveshare Barcode Scanner Module, tilted down 15° behind a flush window in the chin. The unit hangs flat on a wall plate hidden in a recess in its back, the screen 75 mm out from the wall. The plate goes up with four screws, or with four pairs of Command picture-hanging strips where you can't drill. Cables leave underneath.

Files:

• Two print profiles: the whole case on Bambu Studio plates (the shell with its logo on filament 2, the chin lid and the scanner nose; then the back cover, the wall plate and the cleat), and the same with a scanner nose for a Waveshare board whose brass standoffs have come off.

• Every part as its own STL, already lying the way it prints, and front_shell_with_logo.3mf for a two-colour face.

• fit_test_frame.stl: the face's first 8 mm, about an hour, to check the glass fits before the long shell print.

Print settings: 0.20 mm, 4 walls, 5 top and bottom layers, 15 % gyroid, textured PEI plate, no supports, no brim (add a 5 mm brim on the shell if its corners lift). Turn off auto-orient. About 400 g in all. Every part fits a 250 × 210 mm bed. PLA is fine to try it; print the shell and the back cover in PETG for a unit that runs all day, since the Pi and the PoE HAT run warm.

Hardware: one M2.5 screw assortment (4, 6, 8 and 12 mm; each screw cuts its own thread), 4 × M2.5 × 25 mm for the Pi and HAT stack, a right-angle micro-USB to USB-A cable (plug turning down) for the scanner, and a slim Ethernet cable for PoE. Print the wall plate and the cleat first: they show how your printer handles the 0.3 mm sliding fit.

Assembly guide and parts list: https://estokiapp.com/kiosk-case/ (em português: https://estokiapp.com/kiosk-case/pt-br/). It has every part to buy, which screws go where, the ten assembly steps with photos, and how to hang it on the wall.

The software: the kiosk app is free for any Estoki household and installs from Raspberry Pi Imager or one command: estokiapp.com/kiosk. It is not open source; the case is shared on its own, under CC BY-NC 4.0.

The Estoki name and mark in the face are Estoki's; print them on your own case, but don't sell cases or products carrying them.
