HevORT: Duet 3, Raspberry Pi and Fan Mounts on 35mm DIN Rails

prusaprinters

<p>Hello everybody,<br><br>these are mounts for a Duet 3 board, a Raspberry Pi, a 80mm and 92mm Fan.<br>I use a Raspi 4 and fans from BeQuiet!. But other models should fit as well.<br><br>The entire asselby is about 35cm long.<br>So make sure that 35mm DIN Rails fit in your Printer.<br>(For reference: My 365x365 HevORT requires 50cm DIN Rails)<br><br>The mounts clip on standard 35mm DIN Rails.<br>All clips are designed to hold very thight on the DIN Rails.<br>Additional force can be applied by tensioning the clips with M3 screws, but this should not be required.<br><br>The clips also offer lots of opportunity for cable management under the boards and Fans.&nbsp;<br>I added some pictures from different stages of my HevORT build to provide some examples.<br><br><br><strong>Additional Parts required:</strong><br><br><strong>- DIN Rails</strong><br>2x standard 35mm DIN Rails, min 35cm long</p><p>&nbsp;</p><p><strong>-Fan mounts:</strong><br>3x M3x8 screws and 3x M3 nuts each. Longer ones will fit as well.<br>4x Standard screws delivered with your Fan (otherwise M4x30 or longer should work &nbsp;+ 4x M4 nuts)</p><p>&nbsp;</p><p><strong>-Duet 3:</strong><br>4x M4 Screws. They should be no longer than 14mm. Shorter is OK.</p><p>&nbsp;</p><p><strong>-Raspberry Pi:</strong><br>Use the standard screws delivered with our Raspi.&nbsp;<br>These are standard screws you might also use in your PC.<br>I measured the thread at 2.4x3.8mm. So probably M2.5x4mm screws<br><br><br><strong>-Optional Parts:</strong><br>M3x8 screws (10pcs) to tension the clips which snap on the DIN Rail (M3x6 to M3x10 should work as well)<br><br><br><strong>Print Settings:</strong><br>The design was developed with PETG. PLA might be to brittle. The clips might break off if made of PLA.<br>Two perimeters are sufficient. Infill can be chosen low.<br>There are no supports required. If you feel like you need supports the orientation on the printbed might be incorrect.</p><p>&nbsp;</p><p><strong>Files:</strong><br>All files are available as .STL and .STEP<br><br>All designs were created in OnShape and are made public:<br><a href="https://cad.onshape.com/documents/7233f4ec7b52ea6d48da4a3a/w/c558074afb80e1e8027f35f0/e/298820a80fa97e2cf296f2f4">https://cad.onshape.com/documents/7233f4ec7b52ea6d48da4a3a/w/c558074afb80e1e8027f35f0/e/298820a80fa97e2cf296f2f4</a><br><br>There is more stuff in this OnShape project which I will publish later. Also unused / mirrored / untested designs, so be careful to choose the right part.<br>Feel free to create a copy, remix and upload it. Just reference the original design (this post).<br><br>The clip design took inspiration from RobertHunt's work (Thing #101024 on Thingiverse) but was completely redesigend.<br><br><br>Best Regards,<br>Mike</p>
