Just finished uploading the design for the E3D Titan extruder mount on the @LulzBot mini.
I’m currently using the mount and it’s working great. There is a definite quality improvement, and eventually I will switch to 1.75mm which I expect will be even better.
The fan duct needs a bit of work, but it’s usable. There are some restrictions because of the wiper pad.

I’ve always used 1.75 on my machines. Was away for a month and only had access to lulzbot mini’s and thought the 3mm was a waste. So much pressure to feed it in. Not to mention that bulky extruder. I wanna see some before and after prints once you start using 1.75;-) nice work as always @Stephanie_A
Thanks, my biggest disappointment in the lulzbot family is the lack of even an option for 1.75mm from the factory.
Many vendors are switching to 1.75mm and some don’t even produce 3mm, especially in exotic materials. The exotic materials is my main reason for wanting to switch, but the other benefits are many, like a smaller melt chamber and lower pressures.
Aside from flexible there isn’t much advantage to 3mm filament IMO. And even then extruders are quickly making up for it.
Awesome. Could you upload some pictures of it installed?

Thanks!
@Stephanie_A Just printed this and it didn’t fit - which isn’t your fault, my Titan is just… different. Can you share the source files so i can modify them? The .sldprt on Thingiverse are just imported solids, which are not all that useful for adapting them.
Reason I didn’t share it was because I didn’t clean up the workspace yet.
Let me know if there are any problems, OnShape doesn’t provide any “share this” functionality, so the best I can do is copy and paste.
If you have any improvements let me know. I’ve been printing with this for the past few weeks and the difference in quality is astonishing.
The hardest part was rewiring everything. Firmware changes are simple. Stand by the printer and be prepared to shut it off just in case.
Thanks for the share, definitely a good starting point. Let’s see if i feel confident enough to actually redesign this entirely in Onshape.
I’ve already replaced the hotend with a 1.75mm one, so the rewiring process and the suspense of hoping the printer doesn’t bury its nozzle in the wiper pad is familiar to me 
completely redesign? now I’m even more curious!
it actually didn’t take too long to design it, most of my time was spent getting measurements, and making sure the z offset was right (guess what, it wasn’t right the first time, that was exciting!).
the endstop being attached to the fan duct was quite annoying too. I’m running into all the same issues with the TAZ6 that I’m trying to convert.
@Stephanie_A having the correct dimension all in one file already helps a bunch. Though i’m not sure how much I’m allowed to talk about the reason why i need these, suffice it to say that there are a few dimensional changes in the Titan extruder unit i have here.
