<p>This is a remix of <a href="https://www.thingiverse.com/thing:4776565">Ender 3 V2 Drawer replacement</a> from Thingiverse. I've remixed it to fit my setup:<br>RPI4 with POE+ hat<br>Pi Cam cable coming out the back of the RPI.<br><a href="https://www.thingiverse.com/thing:4965525">Hidden nozzle tray</a></p><p>---</p><p>I've been meaning to mount my RPI in the drawer section of <a href="https://www.amazon.com/Official-Creality-3D-Removable-220x220x250MM/dp/B07K3SZBHJ?dchild=1&amp;keywords=ender+3&amp;qid=1612857257&amp;sr=8-1-spons&amp;psc=1&amp;linkCode=ll1&amp;tag=thingiverse09-20&amp;linkId=5419ace64a5f58b068a896710257ed13&amp;language=en_US&amp;ref_=as_li_ss_tl">Ender 3</a> v2 but wasn't able to find something that ticks all the boxes. So I watched some guides on Fusion 360 and made this remix. I've made the following changes:</p><ol><li>Lowered all RPI mounting studs, so there's enough space to put a RPI with POE+ hat in there upside down.</li><li>Removed 40mm fan mounting bracket to make sure RPI has enough clearance. Fan grill is still there.</li><li>Made a cutout for the Pi Cam cable coming out right behind the RPI. Position of it is assuming the RPI is upside down.</li><li>Removed the right side 4040 rail cover that's popping out so I can keep the hidden nozzle tray there.</li><li>Removed the mounting pillars on the lid.</li></ol><p>---</p><p>I'd recommend printing in PETG just in case, RPI4 with POE+ hat runs pretty hot and I have 2 other RPI with POE in PLA cases that's super warped. Wouldn't want a section of my <a href="https://www.amazon.com/Official-Creality-3D-Removable-220x220x250MM/dp/B07K3SZBHJ?dchild=1&amp;keywords=ender+3&amp;qid=1612857257&amp;sr=8-1-spons&amp;psc=1&amp;linkCode=ll1&amp;tag=thingiverse09-20&amp;linkId=5419ace64a5f58b068a896710257ed13&amp;language=en_US&amp;ref_=as_li_ss_tl">Ender 3</a> v2 to be warping after some time.</p><p>&nbsp;</p><p>Notes:</p><p>You need to rotate both models when bringing it into slicer.<br>For base:</p><ol><li>Rotate it bottom down.</li><li>Only support it needs is for the rail at right and back side, and the hooks on top. I just use normal support everywhere with 78 degree overhang angle. Then use support blocker to block out supports in the tiny holes, they don't need support.</li></ol><p>For the lid:</p><ol><li>Rotate it so it sits vertically on the print bed. Look at last pic for reference. That way you can print with least amount of support.</li><li>Only support it needs after you rotate it vertically is the left side curve. I just used the custom support plugin in cura to do that.</li><li>If you rotate it vertically like I did you're gonna want to print with brim. 8 brim lines did just fine for me.</li></ol>
