Inky Impression Pimoroni 13.3" Frame

This frame is designed to fit the Inky Impression 13.3" E-Ink display by Pimoroni with a Raspberry Pi 4 mounted behind it.  The frame allows access to the buttons on the side of the display and has options for wall mounting or table top (with use of the stand).  The frame is assembled with M3 (Qty 12) and M4 (Qty 12) heat set inserts and appropriate length button top or socket cap M3 and M4 screws.  I used the following:

• Qty 8 M4x16 Button Head to assemble the Locking Tabs to the frame
• Qty 4 M4x16 Socket Cap to assemble the Braces to the frame
• Qty 12 M3x6 Button Head to assemble the back covers to the frame

Assembly steps:

1. Install heat set inserts into frame
2. Use the locking tabs and M4 screws to join the two frame halves together.  There is a half round recess in the bottom locking tab which should align with a similar recess in the two frame halves.
3. Place the buttons (4) into the holes on the side of the frame from the in side of the frame.  The rounded end of the button should protrude out the outside of the frame.
4. Insert the Inky Impression display into the back of the frame and place the two braces on top of the display into the recesses on the frame.  There are cutouts on the braces to clear the components on the back of the display.  Make sure these are aligned correctly.
5. Affix the braces to the frame with M4 screws.  DO NOT OVERTIGHTEN THE M4 SCREWS OR YOU COULD DAMAGE THE DISPLAY.  You don't want to damage the display.  Just tighten enough so that there is little or no play between the display the frame and the braces.
6. Choose where you want the power cable to exit the frame and route it through the appropriate cable cutout in the frame.  There is an option for bottom center and either the bottom left or right side.
7. Attach the back covers to the frame using M3 screws.
8. Place the display in the stand or hang it on the wall with the Wall Mount.  If hanging on the wall, it might be a good idea to place some rubber bumpers on the back covers to space the frame off the wall for cooling.  Note that the wall mount was intended to be used with double sided tape or 3M Style Command Strips.  Or you could use a simple nail or picture hanger.

My frame was printed in Bambu Dark Brown Matte PLA on an X1C.  No supports required although I did use a brim on the buttons just in case.  0.4 Nozzle, 0.16 Layers.  Bambu 0.16 mm High Quality Profile with the following global modifications:

• Auto circle contour-hole compensation
• Order of walls - outer/inner
• Sparse infill density - 10%
• I reduced sparse infill to 5% for the stand
• Added an outer brim to the buttons (just in case)

I'm using the frame to house my display running InkyPi designed by faithak/AKV Dev.  See their YouTube video and the InkyPi Git Hub for details on the project.
