1U Raspberry Pi Rack with Moduler trays

prusaprinters

<p>This is a 1u Server Rack design I came up for use with Raspberry Pis. I was inspired by a number of designs out there, especially the one's with lcd screens and reset buttons!  Make sure to print face down. No supports needed! Each 1U shelf should hold six Pis or 3 Pis with HDD tray or some mixture.</p><p>This design is intended to be used with the official POE hat. All trays should allow for that.</p><p><strong>Print Settings</strong><br/>Print face down<br/>No supports needed<br/>.2 layer height<br/>.4 nozzle<br/>Perimeters 5 or 6 on the 1U shelf for strength (you want basically want it to be solid)<br/>Petg filament</p><p><strong>Printable Parts List</strong><br/>A left/middle/right 1u mounting tray you mount in a standard 19" server rack<br/>Pi 4 Trays<br/>Pi 3 Trays<br/>Trays come in a Tray only, Tray with a reset button, Tray with reset and OLED, and Tray with reset, OLED, and led formats.<br/>I've also recently created a tray that has room for a SSD or HDD but takes up two slots.</p><p>New:</p><p>Pi Zero Tray - One for only a Pi Zero and one with a OLED.</p><p><strong>Future ideas</strong><br/>CM4 Tray - In Progress<br/>Rack Mount Make over for CM4 - In Progress<br/>HDD only trays<br/>Moving the pi to the left of the HDD tray<br/>Open to other ideas.</p><p>Below is a list of parts used in the build.</p><p><strong>Button </strong><br/><a href="https://www.amazon.com/dp/B075LDGHHS">DIYhz Momentary Push Button Switch</a></p><p><strong>OLED</strong><br/><a href="https://www.amazon.com/gp/product/B079BN2J8V">OLED Display - MakerFocus 2pcs I2C OLED Display Module 0.91 Inch I2C SSD1306 OLED </a></p><p><strong>RGB LEDs</strong><br/><a href="https://www.amazon.com/gp/product/B01D1FFVOA">ALITOVE 100pcs WS2812B Addressable 5050 smart RGB LED Pixel light on Black Heat Sink </a></p><p><strong>Wires</strong><br/><a href="https://www.amazon.com/gp/product/B01EV70C78">Elegoo EL-CP-004 120pcs Multicolored Dupont Wire</a> </p><p><strong>Hard Drive Adapter</strong><br/><a href="https://www.amazon.com/gp/product/B00HJZJI84">StarTech.com SATA to USB Cable - USB 3.0 to 2.5” SATA III Hard Drive Adapter</a> </p><p><strong>Thumb Screws used as pulls</strong><br/><a href="https://www.amazon.com/gp/product/B01N6AE7V3">uxcell Computer Graphics Card 6-32 Round Head Knurled Thumb Screws Silver Tone 10pcs</a><br/><br/><strong>Offical Raspberry Pi Hat</strong><br/>URL - <a href="https://www.pishop.us/product/raspberry-pi-poe-hat/">https://www.pishop.us/product/raspberry-pi-poe-hat/</a></p><p><strong>4 Pin Header for POE Hat Standoff</strong><br/><a href="https://www.digikey.com/short/r9td90f0">SSQ-102-01-G-D</a></p><p><strong>GPIO Header standoffs</strong><br/><a href="https://www.adafruit.com/product/2223">GPIO Stacking Header for Pi A+/B+/Pi 2/Pi 3 (Extra-long 2x20 Pins)</a></p><p><strong>Screws</strong><br/><a href="https://www.amazon.com/gp/product/B01N9Q8YLE">M2.5 Black Nylon</a> but any M2.5 standoff or nut combo should work.</p><p>Inspired in part by: <a href="https://www.thingiverse.com/thing:3022136">https://www.thingiverse.com/thing:3022136</a> and you can find some hints using this link for the OLED if you need it.<br/><br/>Another guide to setup your OLED can be found <a href="https://learn.adafruit.com/adafruit-pioled-128x32-mini-oled-for-raspberry-pi/usage">here at Adafruit site</a>.</p><h3> </h3><p>Update: </p><p>7-2-2021 - Pi4 tray button only and Pi4 HDD tray with no LCD (IE button only) also tried to improve naming and sorting of the files listed here.</p><p>Also added a 3d printable knob thing but it's tricky to print layer height of .1 seems to work best.  Even then the peg might need some sanding to slide in.  Use super glue to attach.</p><p>8-7-2021 - Pi Zero Trays added.  One with and one without OLED.</p>
