Interlocking Picture Frame for 32in Displays

Overview

I designed a simple frame to slide over the TV I use for my Magic Mirror Smart Hub. I wanted a way to cover the ugly parts of the TV and the wires. It also provides the option to place a two way mirror into the frame should I want to to look more like a mirror.

The frame has been split up into small pieces that can be printed on the Pruse Core One (or larger printers) with interlocking claps, reducing the amount of hardware required for assembly.

I printed these parts on a textured plate to reduce the shininess of the front.

Assembly Information

Required Hardware:

• 2x M2.5x8 SHCS

• 1' of Neoprene Weather Stripping Foam Tape, 1 Inch x 1/8 Inch, cut into 4x 3" strips

1. Print and assemble frame as shown below. Numbers are embossed on the inside of the frame. 

1. Using the interlocking clasps, connect these parts together

NOTE: The holes that accept the clasps can be a bit too tight depending on which printer you use, gently tapping the clasps into place is acceptable.

NOTE: There are sight holes to ensure the parts are full seated.

1. Install Raspberry Pi 4 and affix to frame using 2X M2.5x8mm SHCSs

1. Apply Foam tape to each of the corners of the frame and trim any excess. The tape can be pressed into the corners to avoid having to cut more than 4 strips/

1. Connect power and display to both the RPI4 and the Display

1. Carefully install frame onto the display, note that the frame will need to be shimmied around the RPi4 because of how its located on the frame itself. Route power cables through the channel at the bottom of the frame.

NOTE: The frame should be a gentle friction fit on the screen. If you're noticing the frame is too tight, remove foam tape from two opposing corners and try the installation again.

Misc Notes

I provided all files needed to be able to adjust the shape and size of the display in Solidworks.

The clasp is also fully adjustable, I found the current dimensions of the clasp provides enough strength to hold the frame together while still making it possible to take apart.

This honestly wasn't my cleanest CAD work but it might be a good foundation for your own frame.

For the solidworks files only:

• clasp_negative is linked to connector_clasp, modifying connector_clasp's geometry will update claps_negative

• display_frame is linked to clasp_negative, modifying clasp_negative's geometry will update display_frame

• display_frame is linked to the Raspberry Pi 4's model in display_frame_assy, moving it will update the connector locations and mounting hole locations

Future Updates:

1. Move RPI4 to make installation of frame less of a PITA

2. add accommodations for a power strip inside the frame to hide remaining power cables and power management system

3. Add CAD for the two way mirror acrylic cover (Note that a cut panel should still fit in the current file)
