<p>This is a case for an Einsy Rambo Board with room for a Raspberry Pi 3b/b+/4 and buck converter that fits the Bear Upgrade v-slot frame.</p> <p>STOCK FRAME VERSION: <a href="https://www.prusaprinters.org/prints/30296-einsy-rambo-raspberry-pi-case-for-stock-frame">https://www.prusaprinters.org/prints/30296-einsy-rambo-raspberry-pi-case-for-stock-frame</a></p> <h3>Does not require extended PSU wiring!</h3> <p>The Einsy board is positioned at the same height as in the stock Prusa Einsy box, so the stock PSU wires will reach.</p> <p>Supports connecting Pi via USB or GPIO.</p> <p>Supports wiring for MMU2.</p> <p>Update 02-21-2020:<br/> All parts with "2-20-2020" in the file name now print WITHOUT SUPPORTS! Even the Lid!<br/> Increased wall thickness of box sides to stiffen it up.<br/> Added more space between the Einsy and RasPi boards to make it easier to connect the GPIO on the Pi.<br/> Lots of other small changes and improvements.</p> <p>Update 09-14-2019:<br/> I finally got around to installing the Bear X-axis on my printer, and what do you know the board box was interfering with the X motor. I have fixed this by moving the entire box inboard 3mm.<br/> I also added slots for square nuts at the cover fasteners.</p> <p>Update 07-09-2019:<br/> Added version for Raspberry Pi 4 (untested by me but should work)</p> <p>Update 07-04-2019:<br/> Increased clearance to x-axis motor.<br/> Optimized features for FDM printing.</p> <p>Update 06-24-2019:<br/> Added optional cover with mount for 40x40x10 fan.</p> <h3>Print instructions</h3><p>0.20 layers<br/> PETG or other heat resistant material</p> <p>Print with supports on the V1 covers only.</p> <p>All parts with "2-20-2020" in the file name print WITHOUT SUPPORTS.</p> <p>Bridging on the lid works best with no more than 2 perimeters.</p> <h3>To mount to Bear frame:</h3> <p>3x M5x8 bolts<br/> 3x M5 tee nuts<br/> 2x M3x10 hex nuts<br/> 2x printed drop-in tee nuts*<br/> 2x M3 hex nuts (for drop in tee nuts)</p> <p>*printable drop-in tee nuts:<br/> <a href="https://www.thingiverse.com/thing:3050607">https://www.thingiverse.com/thing:3050607</a></p> <h3>Extruder and heatbed wire bundle clamps:</h3> <p>4x M3 square nuts<br/> 4x M3x10 socket head screws</p> <h3>To mount Einsy:</h3> <p>4x M3x10 socket head screws<br/> 4x M3 hex nuts</p> <h3>To mount Pi:</h3> <p>3x M3x10 socket head screws<br/> (holes in Pi are undersized; drill them out to 3mm)</p> <h3>To mount buck converter:</h3> <p>2x M3x10 socket head screws</p> <h3>To attach cover:</h3> <p>4x M3x10 socket head screws<br/> 4x M3 square nuts</p> <h3>To mount fan:</h3> <p>4x M3x12 socket head screws<br/> 4x M3 hex nuts<br/> or<br/> 4x fan mount screws (see picture. comes with noctua fans)</p> <p>All slots for square nuts are sized to fit the thicker (2.35mm thick) square nuts commonly sold on amazon.</p> <p>This buck converter fits:<br/> <a href="https://www.amazon.com/gp/product/B06XRN7NFQ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1">https://www.amazon.com/gp/product/B06XRN7NFQ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1</a></p> <p>This fan fits:<br/> <a href="https://www.amazon.com/gp/product/B00NEMGCIA/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1">https://www.amazon.com/gp/product/B00NEMGCIA/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1</a></p> <p>STEP file included.
