<p style="margin: 0.1rem 0; line-height: 1.0;">The brand is AC Infinity, it's really an auxiliary electronics cooling fan (you put it on the outside of the case of routers, TVs, VCRs, gaming consoles, etc. to cool them). The fan is 5v DC with a USB connector. I picked it because out of all the radial fans I tested this one had the lowest noise profile.</p>

<div dir="ltr">Hi Ian,</div>
<div dir="ltr"> </div>
<div dir="ltr">Is that an A/C fan? Jon, I think that’s the same can I used on Snoopy, and it worked well for 2 people. The fan adapter was just a flat plate with a pressure fit hole in it if I remember correctly.</div>

<div dir="ltr">The key regarding the fan is that it be radial rather than axial. I can look up a specific one if you like.</div>

<p style="margin: 0.1rem 0; line-height: 1.0;">Hi Jon,</p>
<p style="margin: 0.1rem 0; line-height: 1.0;"> </p>
<p style="margin: 0.1rem 0; line-height: 1.0;">this is the canister filter I went with (similar to those on other psubs):</p>

<p style="margin: 0.1rem 0; line-height: 1.0;"> </p>
<p style="margin: 0.1rem 0; line-height: 1.0;">And this fan (because it's really quiet):</p>
<p style="margin: 0.1rem 0; line-height: 1.0;"><a href="https://www.amazon.com/gp/product/B012CL2V3I">https://www.amazon.com/gp/product/B012CL2V3I</a></p>
<p style="margin: 0.1rem 0; line-height: 1.0;"> </p>
<p style="margin: 0.1rem 0; line-height: 1.0;">I 3D printed a simple adapter to mate the fan to the canister, but this could be made from a piece of scrap wood. I can share the 3D model for the adapter if anybody is interested.</p>
<p style="margin: 0.1rem 0; line-height: 1.0;"> </p>
<p style="margin: 0.1rem 0; line-height: 1.0;">As for CAD software, I've been mainly using OpenSCAD, which is a 3D scripting (kind of a "functional" programming) language. If you are coming from a programming background you might find OpenSCAD more tractable than having to come to terms with the idiosyncrasies which ever CAD package you have access to. </p>

<div dir="ltr" data-setdir="false">Hey guys, I'm in the initial thought processes of CO2 scrubber design and really don't want to reinvent the wheel on this component. Are any of you willing to share some details on your design? I know Alec submitted a 3D printer design which we have on the website however I don't have access to a 3D printer and frankly even though I've spent 40+ years in software development and can modify a UNIX kernel, my CAD skills are pretty much non-existent.</div>
<div dir="ltr" data-setdir="false"> </div>
<div dir="ltr" data-setdir="false">For this component I'd really like something that can be built with as many off the shelf parts as possible. Any suggestions?</div>
