Big Einsy Case for Raspberry Pi Zero W 2

prusaprinters

<p>I really like Boogie's Big Einsy case with BF3Design's remix, and this is just a minor remix, but with the RPi Zero W 2 it makes a big difference!&nbsp; By routing the LCD screen ribbon cable along the right side of the box you can mount the RPi Zero on the front of the Einsy board.&nbsp; This allows space to put a heat sink on the RPi, gives access to the RPi microSD card, webcam connector and USB connectors, and you can see the RPi status LED.</p><p>There are a few zip tie anchors in strategic locations to help with cable management and avoid having loose wires.&nbsp; The most important is at the top of the case to hold the PINDA cable. &nbsp;It takes a little jiggling but the Einsy board can fit past this zip tie and the ribbon cable support.<br>&nbsp;</p><p>The GPIO connection on the Einsy board needs to be extended. &nbsp;I used a "2x20-pin Extra Tall Female Stacking Header 0.1" for Raspberry Pi" except cut it to be 2x7 pins, see photo for installation. &nbsp;The RPi carrier needs (1) M2.5x8 socket head for inside the case and (1) M2.5x8 countersunk for the top. &nbsp;The threads are printed in the carrier and case, so it was hard to get the screws in. &nbsp;I put them in before assembling the box to open up the threads a little first.</p><p>The RPi heat sink is flush with the front cover, so I revised the cover with a cutout, and changed the fan mounting. &nbsp;A 4010 fan fits nicely with (2) M3x20 countersunk screws. &nbsp;This change also allows the cover to be printed without supports, but its three pieces.</p><p>I printed with Overture Clear PETG, 3 perimeters and shells, 15% gyroid infill. &nbsp;It doesn't look great in the photos, but in real life it looks really nice, and its translucent so its easy to see the LEDs.</p><p>The BOM is the same as BF3Design's.</p><p>You'll need to download einsycase_cable_cover_1.stl and einsycase_cable_cover_2.stl files from the original model : <a href="https://www.prusaprinters.org/fr/prints/31558-big-einsy-case/files">https://www.prusaprinters.org/fr/prints/31558-big-einsy-case/files</a></p><p>I monitored the temperature of the RPi and with the RPi camera and a ribbon cable going up under the cover of the box it reached 60 C, using a webcam it was about 51 C, and running the fan cooled it to 36 C with a 18 C ambient temperature.&nbsp;</p><p>Edit- I found that the fan screen causes a high pitched whiny noise. &nbsp;I tested alternate screens on my Bear mod which does not have a heat sink on the RPi. &nbsp;I designed alternate “aero inlet” and “simple bezel” and recorded the RPi temps during a print. &nbsp;The original screen had the highest temp at 35.9 C, with the bezel at 34.3 C, no noise, and the aero at 33.8 C and a little noise. &nbsp;I have included these stl files as well, and I am now using the simple bezel.</p>
