Waveshare 7.3-inch e-Paper Slim Fit Portrait Frame

📌 Why This Frame Exists

While there are many e-Paper mounting frames online, this design focuses on practicality and usability for makers using:

✔ Prusa MINI and similar printers — fits within a 180-mm build volume.
✔ Portrait orientation — perfect for wall mounting or vertical display installations (landscape option included, though).
✔ Fully 3D-printed — no IKEA parts, brackets, or external hardware required.
✔ Balanced and symmetric design — top = bottom and left = right margins for visual harmony.
✔ Room for electronics behind the display — ample internal space to house cabling, Waveshare HAT, and a Raspberry Pi Zero 2 W comfortably.

This frame isn’t just about holding the panel — it’s about making a complete wall-mounted e-Ink display that’s simple to print, assemble, and install.

🛠 Details & Features

• Slim bezel: Clean modern look while still structurally robust

• Portrait orientation: Optimized for vertical hanging

• Integrated mounting point: Screw boss/hanger hole ready

• Cable space behind frame: No squeezing or sacrificing electronics

• Designed on constraints: Sized for smaller printers without splitting or seams

🖨 Printing Notes

Note: No cable pass-through is included in the STL. For external power (e.g., USB cable), you can add a small round opening in your slicer before printing, or drill/file one afterward where convenient.

📦 Files Included: STL and gCODE files for the following:

• Front frame (vertical, but landscape option also available: pick one).

  • Note that this will be the only part visible to the eye. Choose your preferred color here.

• Display backboard.

• 2× crossbar.

• Optional: 1× cable tidy and 1× RPi clip.

⚙ Recommended Printing

• Printer: Prusa MINI or any printer with ≥180 mm max print length.

• Material: PLA (PETG if exposed to sunlight).

• Supports: None — built-in geometry avoids complex support zones.

🛠 Assembly

1. Turn the frame front-down; drop in the display and the backboard after it. Take care to align the display's wire strap with the rounded section of the backboard. The backboard has extra raised margin on the other side, which helps center the active display area.

2. Click the two crossbars in place. This holds the backboard with the display securely in place.

3. Check the positioning of the display from the front. There's very little leeway and if it's off, it will be just by a sub-mm offset. Adjust it with your fingers.

4. Optionally secure the strap with the cable tidy; fix it with double-sided tape, glue or regular tape

5. Optionally secure the electronics with the RPi clip; fix it with double-sided tape, glue or regular tape

🧩 Final notes

I was originally inspired to do this project by the listing from DIY Machines. I quickly realised I wanted to do my own not only in hardware, but also in software. For most builders I guess InkyPI is quite serviceable but I made my own spaghetto in BASH with a heavy use of Imagemagick, GNUPlot and AWK. The code is too specific to publish, but feel free to ask if you’d like pointers.
