Basically looking for legacy parts for my kittaz (Taz3) as I try to build a quick swap extruder assembly for softer filament. I’d like to add this fan and funnel combo as per the standard extruder assembly. Is there a database of legacy parts (.stl) that I can print? what about the make and model of fan? or maybe it’s just a generic 40x40mm fan?
https://download.lulzbot.com/ is the place to look for files for the STL files for all the printable parts for older Lulzbot printer. You might have to do a bit of searching to find what you want but it should be there somewhere.
I believe it is just a generic 40x40x10mm fan. Of course, you can’t tell from the picture what the voltage rating is.

A couple of years ago I acquired a Taz 3 from a friend. Here’s the cooling fan shroud I downloaded from Lulzbot.
fan_mount_3_ss.STL (1.3 MB)
Yep, that’s the one, thanks so much TM, now I just have to source a little 40x40 fan 
Assuming it’s 24v? or does it step it down to 5 or 12v? Anyone know?
Yeah I see a few listed on ebay, I wonder if it’s 24v or stepped down to 12 or 5v?
I guess this answers the question…
Great. Yeah those are 24v, seems like the smaller “blower” type are 5v…go figure.
So any idea if they have that fan shroud in the native .sldprt file anyway? Shouldn’t be too difficult to model anyway but would save some time. I realize i’ll have to just extend it down a bit since my hot end is longer on this extruder build…
I have the STEP file for the fan shroud but the forum will not allow it to be uploaded. Send me your email address and I’ll forward it to you.
BTW, here’s how I made a quick mod with my 3D modeler. I’d upload a short video but again, not allowed.

This is the standard fan duct on several TAZ models (same on my TAZ5). TBH it isn’t a great fan duct, if you have to make a new one check out some options on Thingiverse etc. Fan is a standard 40x40x10. Voltage should be selectable on the mother board (it was on mine) so you can change it to 24V if it is currently (haha) lower.
