A custom Waveshare 7-inch case that you can 3D print transforms a bare display module into a polished, functional device ready for deployment. Whether you are building a Raspberry Pi dashboard, kiosk display, or portable monitor, a well-designed 3D printed enclosure provides protection, mounting options, and a professional appearance. This guide covers design considerations, printing tips, and popular case designs for Waveshare 7-inch displays.

Waveshare 7-Inch Display Models
Waveshare produces several 7-inch display variants, and your case design must match the exact model. The most common is the 7-inch HDMI LCD (C) with a 1024×600 resolution, capacitive touch, and HDMI input. Other variants include DSI-connected displays for a cleaner cable setup and IPS panels for wider viewing angles. Before designing or downloading a case, verify your display’s exact model number, PCB dimensions, and connector positions.
Key measurements to note include the display active area (typically 154.2 x 86.6 mm for 7-inch), the PCB dimensions (usually larger than the active area by 5-15mm on each side), mounting hole positions, and connector locations (HDMI, USB touch, power, and ribbon cable).
Design Considerations for Display Cases
When designing a case for any Waveshare display, consider thermal management (leave ventilation slots or openings near the processor area), cable routing (HDMI and USB cables need clearance for plugging and unplugging), touch panel access (ensure the case does not obstruct the touch-sensitive area), and mounting for the Raspberry Pi (many designs incorporate a Pi mount on the back for a clean, all-in-one unit).
The case should be designed in two parts (front bezel and rear shell) for easy assembly and maintenance. Use M3 screws or snap-fit joints to hold the parts together. Snap-fits are faster for prototyping but less durable for permanent installations.
Desktop Stand Design
A desktop stand case tilts the display at 15 to 30 degrees for comfortable viewing. The stand can be integrated into the rear shell or designed as a separate kickstand piece. For a Raspberry Pi dashboard or home automation panel, a desk stand with the Pi mounted on the back creates a clean, self-contained unit.
Design the stand with a cable exit at the bottom for a tidy appearance. Include a slot for a power cable and HDMI cable, routing them down through the stand base. The stand’s base should be wide enough to prevent tipping, with non-slip pads (printed with TPU or added as stick-on feet) on the bottom.
Wall Mount Design
Wall-mounted displays work well for home automation control panels, information displays, and digital signage. The wall mount case should include a flush mounting plate with screw holes that attach to the wall, a removable face plate for accessing the display and Pi for maintenance, and cable routing through the back plate with a cutout for wall-recessed cables.
For Indian conditions, consider adding dust protection with a gasket channel in the front bezel. A simple 1mm TPU gasket between the bezel and display prevents dust ingress in dusty environments like workshops and industrial settings.
VESA Mount Adapter
A VESA mount adapter allows you to attach the Waveshare display to any standard monitor arm or wall mount. Design a 75mm or 100mm VESA pattern plate that attaches to the display case’s rear. This is particularly useful for adjustable-height setups in workshops, standing desks, or kiosk applications.
The VESA adapter should use M4 threaded inserts (heat-set into the 3D print) for reliable mounting. The adapter plate needs to support the combined weight of the display, case, and Raspberry Pi, so print it with at least 4 perimeters and 40 percent infill for strength.
3D Printing Tips for Display Cases
Print display cases with the following settings for best results. Use PLA+ or PETG filament for dimensional accuracy and stiffness. Set layer height to 0.2mm for a good balance of quality and speed. Use 3 to 4 perimeters for structural strength. Set infill to 20 to 30 percent (higher for load-bearing areas). Print the front bezel face-down on the build plate for a smooth, scratch-free surface against the display.
Post-processing makes a significant difference in appearance. Light sanding with 220 to 400 grit sandpaper smooths layer lines. A coat of filler primer followed by spray paint creates a factory-finished look. For a quick professional finish without painting, print in black PLA+ which hides layer lines well.
Frequently Asked Questions
What is the best filament for a display case?
PLA+ offers the best dimensional accuracy and surface finish for display cases. If the case will be exposed to heat (near a window in Indian summer), use PETG which has a higher heat deflection temperature. Avoid ABS for display cases as it warps easily and gives off odours during printing.
How do I ensure accurate dimensions for a tight fit?
Calibrate your printer’s XY dimensions first using a calibration cube. Add 0.2 to 0.3mm tolerance to all mating surfaces. The display should slide into the case without force but without excessive play. Test-print a small corner section first before printing the full case.
Can I use the 3D printing service at Zbotic for display cases?
Yes, Zbotic offers 3D printing services where you can upload your STL file and receive a professionally printed case. This is ideal if you do not own a 3D printer or need a higher-quality finish than your home printer provides. Visit Zbotic’s 3D Printing Service for pricing and options.
Conclusion
A custom 3D printed case elevates your Waveshare display project from prototype to product. Choose a design that matches your mounting needs, whether desk stand, wall mount, or VESA adapter, and print it with quality filament for a professional result. The combination of Waveshare displays with custom 3D printed enclosures opens up countless possibilities for dashboards, kiosks, and smart home panels.
