TrailCurrent Milepost — 3D Printed Wall Plate & Screen Housing

A two-piece 3D printed enclosure set designed to mount a 7-inch touchscreen display cleanly to any wall or flat surface. Printed in ABS filament at 100% infill for maximum rigidity and long-term durability in mobile environments.

What's Included

• Wall Plate — the outer trim piece that mounts flush against your wall
• Screen Housing — the inner shell that cradles the display electronics

That's it. Two pieces. Ready to go with your provided electronics and screws.

What's NOT Included

This listing is for the printed enclosure only. The following are not included and must be sourced separately:

• The 7-inch touchscreen display (Waveshare ESP32-S3-Touch-LCD-7B)
• The 12V-to-5V buck converter
• Wiring, connectors, fasteners, or CAN bus hardware
• Any electronics of any kind
• Mounting hardware or Locking Screws

Print Specs

• Material: ABS filament — chosen for heat tolerance and impact resistance in vehicle interiors
• Infill: 100% — solid throughout, no soft spots
• Finish: As-printed. Layer lines will be visible on all surfaces. These parts are not sanded, vapor-smoothed, or painted. If a flawless injection-molded appearance is important to you, this product is not for you.

Who This Is For

Makers and RV builders who already have (or plan to buy) the Milepost display and electronics and want a clean, purpose-built enclosure to mount them. The two-piece design lets you route wiring and fasten the screen housing to the wall plate after your electronics are in place.

TrailCurrent is open hardware. Print files, firmware, and documentation are freely available if you'd rather print your own.
