A 3D-printed, arcade-style slide-in wall mount is one of the more popular ways makers are enclosing a Raspberry Pi 4 or 5 in 2026: the board slides into a printed tray, the tray slides into a wall-mounted shell, and the whole thing looks intentional instead of like a bare board zip-tied behind a monitor. Here's what actually matters when designing, printing and installing one — fit, print settings, thermals, and the cabling details that get skipped in most quick tutorials.
Why Wall-Mount a Raspberry Pi in the First Place
A wall-mounted Pi clears desk space for a media center, retro-arcade controller, home automation hub, or a always-on server tucked behind a TV or monitor. The tradeoffs versus a desktop or shelf enclosure are mostly about access and airflow: a wall mount is harder to reach for SD-card swaps and re-cabling, so the connector layout and cable routing need to be right before it goes on the wall, and a case flush against drywall has less passive airflow than one sitting in open air on a desk.
Related builds worth reading if you're picking a Pi enclosure project: a Raspberry Pi 4 AirPlay receiver, a Raspberry Pi Zero cyberdeck, and a look at whether a Raspberry Pi 4 8GB can run local LLMs — all of which depend on the same enclosure and thermal tradeoffs discussed below.
Fit and Compatibility: Pi 4 vs Pi 5 in the Same Case
According to Raspberry Pi's official Pi 5 product page and Pi 4 product page, both boards use the same 85mm x 56mm footprint and standard four-hole mounting pattern that's been consistent across Pi models for years — which is why a huge number of Pi 3/4/5 case designs claim compatibility across generations. But footprint compatibility isn't the same as port compatibility:
| Detail | Raspberry Pi 4 | Raspberry Pi 5 |
|---|---|---|
| Board footprint | 85mm x 56mm | 85mm x 56mm |
| Power connector | USB-C | USB-C (higmoved position) |
| Display/camera connectors | 2x micro-HDMI, 2-lane MIPI | 2x micro-HDMI, dual 4-lane MIPI |
| New connector | — | PCIe FFC (for NVMe HATs) |
| Official docs | raspberrypi.com | raspberrypi.com |
A slide-in case designed only for the outline will physically hold either board, but the USB-C power cutout, the micro-HDMI cutouts and the GPIO access slot need to line up with whichever board's connector layout the design targets. If a listing or model claims "universal Pi 4/5 fit," check whether it actually has offset or dual-position cutouts, or just a generously oversized single cutout — the latter is the more common (and more reliable) real-world solution among the community designs indexed on Printables and Thingiverse.
3D Printing Parameters for a Slide-In Wall Mount
The slide mechanism is the part of an arcade-style case that actually needs tuned print settings — the outer shell tolerances matter less than the channel the tray slides through. General slicer guidance from Prusa's print settings documentation and mainstream FDM practice gives a reasonable starting point:
| Setting | Typical starting value | Why it matters here |
|---|---|---|
| Nozzle diameter | 0.4mm | Standard nozzle size on most consumer FDM printers; fine enough detail for connector cutouts |
| Layer height | 0.16–0.2mm | Finer layers give smoother slide-channel walls with less post-print sanding |
| Infill | 15–25% | Enough structural rigidity for a wall-mounted shell without excess print time |
| Wall/perimeter count | 3+ | Extra perimeters around the slide channel resist wear from repeated insertion |
| Bed temperature | Per filament spec | Follow the filament manufacturer's recommended bed temp to reduce warping on larger flat bases |
Treat any specific tolerance numbers quoted in a downloaded model's instructions as a starting point, not a guarantee — printer calibration, filament brand and even ambient humidity shift dimensional accuracy enough that a slide-fit part usually needs one test print of just the channel before committing to the full case. If the tray is too tight after the first print, most slicers let you add a small horizontal expansion/contraction offset rather than re-designing the model.
Installation: Mounting a Slide-In Case on a Wall
- Mark and drill anchor points. Most wall-mount case designs use either a keyhole slot (hangs on a single screw) or a two/four-hole pattern matching drywall anchors or a stud. Confirm the hole spacing against the STL/model file before drilling — don't eyeball it.
- Mount the empty shell first, then slide the Pi tray in after the shell is secured. Trying to mount a fully-loaded case one-handed is how connectors get cracked.
- Route cables before final assembly. Power (USB-C) and any wired network or peripheral cables should have enough slack to reach the case with the tray slid fully in — measure a folded-back service loop, not a straight line, so the tray can be pulled partway out later for maintenance without disconnecting everything.
- Use a surge-protected outlet near the mount point rather than a bare cable run to a far outlet; a compact wall unit like the QINLIANF 5-outlet surge protector with USB charging keeps the Pi's power adapter and any accessory USB devices on one protected strip close to the install.
- Add wired networking if the install needs it. A Pi mounted near existing network drops is a good candidate for a small multi-gig switch rather than relying on Wi-Fi alone — see the TP-Link TL-SG105S-M2 5-port 2.5G switch or the 8-port TL-SG108S-M2 for compact, wall-adjacent options, and the TL-SX1008 8-port 10G switch if the mounted Pi is acting as a network hub for other gear.
Customization: Materials, Ventilation and Variants
Most community-published slide-in case files are parametric — typically OpenSCAD or Fusion 360 source with adjustable variables for board revision, wall thickness and port offsets — which is what lets a single published design claim both Pi 4 and Pi 5 support. Before printing, check the source files (not just the pre-sliced STL) for a board-select variable rather than assuming a single STL covers both.
Material choice affects both durability and thermal behavior:
- PLA — easiest to print, adequate for indoor rooms at normal temperature, but softens at lower temperatures than PETG or ABS, which matters if the case sits somewhere that gets warm (near a TV, in an attic-adjacent closet, in direct sun through a window).
- PETG — better heat resistance and layer adhesion, still prints on an open-bed printer without an enclosure, and is the common recommendation for anything semi-outdoor or near a heat source.
- ABS — most heat- and impact-resistant of the three, but needs an enclosed print chamber to avoid warping on a base this size, so it's a bigger step up in printing difficulty than the payoff usually justifies for a home wall mount.
Ventilation is a design choice, not an afterthought: an enclosed slide-in shell with no vent slots traps heat against the board, and both the Pi 4 and Pi 5 will thermal-throttle under sustained load well before reaching damaging temperatures. Cutting slots on at least two faces — ideally one low (intake) and one high (exhaust) — lets convection do passive cooling; for any install expected to run CPU-heavy workloads continuously, pairing the case with an active cooler (official Pi 5 active cooler, or an equivalent heatsink/fan for Pi 4) is worth the extra bulk. Ambient LED accents are a common finishing touch on arcade-style designs — a diffuser channel fed by an addressable strip works well as long as it's routed clear of the vent path; general-purpose LED strip lighting like Twinkle Star's 300-LED string can be repurposed in short cut segments for this if a design doesn't call for a specific addressable strip.
For a related retro-styled build using a Pi as the core, see the SNES Classic vs Genesis Mini vs RetroPie comparison — a wall-mounted, arcade-style case is a natural enclosure choice for a RetroPie build specifically. If networking or headless setup is part of the plan, the driverless USB Wi-Fi adapter build on a Pi Pico W and the Raspberry Pi cyberdeck parts list both cover adjacent cabling and power questions. For students or first-time builders picking a project to justify the case, the best Raspberry Pi projects for students in 2026 is a useful starting index.
FAQ
Does a Raspberry Pi 4 case fit a Pi 5? Only if the design accounts for both boards' connector layouts, not just the shared footprint — see the fit table above.
What nozzle and layer height should I use? A 0.4mm nozzle with 0.16–0.2mm layers is the common starting point for a functional slide-fit part; test the slide channel alone before printing the full case.
PLA, PETG, or ABS? PLA for simple indoor installs, PETG if heat resistance matters, ABS only if the extra printing difficulty (enclosed chamber) is worth the added durability.
How do I stop the case from overheating? Add vent slots on at least two faces and consider an active cooler for sustained workloads.
How do I run power and networking to a wall-mounted Pi? Route cables through conduit or a cord cover, use a surge-protected outlet near the mount, and add a compact multi-gig switch if wired networking is needed.
Can I add RGB lighting? Yes, most designs leave room for a diffuser channel fed by an LED strip, kept clear of ventilation slots.
