Collisto's Ender 3v2 Hot End Cover

prusaprinters

<p>As those of us with Ender 3v2 machines will find out, the stock cooling duct will slowly deform and melt causing us to replace it. &nbsp;Many of us have looked for replacements, upgrades and anything else useful to fix this. &nbsp;I have ran other common hot end covers you find out there, but often, these are just big and bulky. &nbsp;I wanted to not have something in the way of a CL touch using the CL touch bracket, and I wanted the cover to be magnetically held on so I can easily access the hot end. &nbsp;This cover and shroud design features (2) 3010 blowers, available on Amazon or many other retailers, (1) 3010 Front Cooling fan(In my case RGB). &nbsp;The great thing with this design is the removable and replaceable cooling ducts. &nbsp;You can print and keep a couple in the drawer so if one starts to deform or melt, you simple pull out one screw and replace. &nbsp;This also means you can print this in two tone, or multiple colors/pieces. &nbsp;I will be honest and say you will source a hand full of parts, mostly screws, magnets, thread inserts, but once done, it looks rather cool, and works at least as good as stock if not better.<br><br>Printing… I have found printing this with the top of the body down onto the bed, and manually entering a few supports is needed. &nbsp;The vents I run next to each other standing up with a brim, &nbsp;some decently placed supports and auto support only to baseplate at 60 or so degrees. &nbsp;The back mounts will print fine without support. &nbsp;Some minor clean up might be required before assembly. &nbsp;See pictures of a finished part below. &nbsp;Magnets are Ø8mm x 2mm. &nbsp;Screws for fans are all 2mm of different lengths. &nbsp;Brass Thread inserts are mostly 2mm threads(Ø3.5mm OD) x 3mm long. &nbsp;Screws and brass thread inserts for back mount are 3mm.<br><br>This is all first public release of Rev A, any updates, changes will be released in future rev updates as I see fit.<br><br>By the way, as many of you designers know, this take a good amount of time, effort and prototyping to come up with these plans. &nbsp;I am offering all STL's for free, you may do as you wish with them following license type. &nbsp;If you find them as useful as I have, consider tipping, and not just for me, but any other artist, designer, maker that provides you free content.<br><br>Update 3/26/22 &nbsp;<a href="https://www.prusaprinters.org/prints/155299-fan-adapters-for-collisto-head-cover">https://www.prusaprinters.org/prints/155299-fan-adapters-for-collisto-head-cover</a> &nbsp;Designed New adapters allowing 40mm fan usage. &nbsp;These are modular and add on to the original design shown here. &nbsp;</p>
