Magnetic CYD Display Mount for Dell P3424WE Monitor

I designed this to make use of the otherwise unused soundbar mounting area on the Dell P3424WE 34" Curved USB-C Hub Monitor. The mount attaches to the monitor's soundbar mounting points and holds a CYD display in a compact, easily removable enclosure.

The display is held in place using three 6 × 3 mm magnets, allowing it to be removed when needed while keeping it securely positioned during normal use.

The CYD enclosure consists of a front and rear printed part, with the two halves secured using M2 hardware. This design is sparce to allow access to ports and buttons and to fit several variantsof the board.

Important CYD compatibility warning: This has only been tested with the two CYD boards shown in the photos. I cannot guarantee compatibility with every ESP32-2432S028/CYD variant.

Although these boards are commonly sold as the ESP32-2432S028 / 2.8" CYD, there are multiple revisions and variants with different component placements, connectors etc. Please compare your board with the photos before printing. In particular, check the positions of the USB connectors, speaker connector, SD card slot, buttons and other components around the PCB.

The mount is designed specifically around the Dell P3424WE monitor's integrated soundbar mounting points. Dell lists the P3424WE as compatible with its magnetic SB521A soundbar mounting system.

The magnetic attachment makes the display convenient to remove, but it is not intended to be a permanent or high-security mounting system. Avoid pulling or knocking the display sideways, and take care when moving or adjusting the monitor.

The display shown in the photographs has been intentionally blurred to obscure its contents.

How to Print

Print:

• Screen Case Mount v1 Front

• Screen Case Mount v1 Rear

Suggested print settings

• These parts were printed in PLA.

• Layer height: 0.25 mm

• 3 walls

• 20% infill

• Supports: Not required for the parts shown

Depending on your printer's tolerances, you may need to slightly adjust the fit around the CYD PCB or screw holes.

Hardware Required

• 3 × 6 mm × 3 mm magnets

• 4 × M2 × 10 mm screws

• 4 × M2 heat-set inserts

Assembly

• Install the four M2 heat-set inserts into the holes on the rear side of the front panel.

• Install the three 6 × 3 mm magnets.

• Place the CYD PCB into the front housing.

• Fit the rear cover.

• Secure the front and rear sections using the M2 hardware.

• Attach the completed display assembly to the monitor mount.

Check the polarity/orientation of the three magnets before installing them. Test-fit the magnets before permanently securing them, particularly if using adhesive. For my use friction fit was sufficient.

Do not overtighten the screws as this could damage the CYD.
