One thing I did find out the hard way...
Ultem = PEI
Aka if you print PEI on a PEI bed, you're gonna have REALLY good bed adhesion...

What have you 3D printed for your TJ?

I have a new GMC Sierra with the "special" GMC tailgate. The tailgate had 4 blanking plates that can be customized with lights or a completely separate audio system for tailgating etc. I have neither. A guy on the GMC forum makes small storage boxes that fit in the recess after you remove the blanking plate. I ordered some and I am very impressed with the quality. I asked what printer he was using because I was considering a P1s. Thats exactly what he uses. I'm bleeding cash right now so its going to have to wait a bit.
My ender had a glass bed and the Bambu has the textured PEI. The glass bed was incredibly sticky and in fact I couldn't figure out how to get PETG to stick without ripping off the coating. The PEI bed, I've noticed on usually thin areas, I won't have as much adhesion and coupled with the cheap Amazon filaments, that I just have on hand that I'm working with for practice, I've had some failures. So far my failures were from changing the way the Bambu does supports and I kept losing some adhesion on thin long area. I think the adhesion is also related to just how fast that thing prints. I was watching it last night and when that thing is printing the infill, it's vibrating like crazy, so I just increased my infill and the problem went away and the part really needed it anyway.
I do prefer the PEI bed though, because the glass bed was too sticky. I had to put stuff in the freezer and it was still difficult to release, so maybe keep that in mind if you're having issues with stuff sticking, but I think the PEI is an ideal compromise.
The printer for me is hopefully the last part of my bleeding money for awhile. I will be experimenting with filaments, but not dropping that kind of $$$ for awhile. IMO the printer cost less than a typical laptop I'd get and I tend to use a printer more than my non-work laptop.
I guess it's all perspective. On top of that I find myself needing random pieces of plastic and usually finding those pieces of plastic are minimum $20 and on some older vehicle stuff and when it comes to experimental projects, I find myself sometimes ordering all kinds of various boxes and stuff in the past wasting days if not weeks trying to get the perfect fit/form and probably spend $100+ getting the right box/panel, but now I will mainly just lose a little bit of time.
In any case this is just a very versatile tool and I drop all kinds of $$$ on tools and I've run into instances where factory parts are actually plastic and I know my sister had to wait months without her new vehicle for a plastic housing. With 3D scanning, I hope to be able to print some of that stuff for at least temporary use and that's another reason why I am interested in ABS and some of the more structural filaments as well.
I normally use the PEI bed for most prints below 350°C. The powder coat bed works well for polycarbonate as well. Magigoo PC makes bed adhesion really good on both beds with polycarbonate, and the parts just pop themselves off as the bed cools off after the print is done.
The problem I had printing PEI is that the filament I was printing was the same material as the bed itself (PEI). (So I had inadvertently welded the part to the bed.)
Getting Ultem to stick to the powdercoated bed was difficult, but there are some good adhesives out there that work well. Key is to keep the enclosure temp at least 90°C (110°+ would be better) and the bed temp at least 155°C, along with adhesive.
Intake adapter nipple for the crankcase ventilation intake.
Quick and dirty solution until I can print the entire intake tube.
Printed in Lexan filament (unblended polycarbonate) on a hot rodded Prusa like most of my other stuff.

Nice. Do you have a file you'd care to share (or sell) over on this thread?
I’ll see if I can upload an STL later.
Literally just three circular extrusions and three chamfers. 32mm OD base 4mm high, 14mm OD stem about 32mm long, 8mm center hole, 1mm chamfers on the base, 0.5mm on the transition, and 1mm 75-degree chamfer on the tip.
Also for anyone wanting to try and make their own parts, Autodesk Fusion 360 is free for hobbyist use with a number of limitations. Just make an account and download. There are free tutorials available. Not quite as easy as Autodesk Inventor or Dassault Systemes SolidWorks, but probably on par with Creo Parametric or AutoCAD in terms of difficulty.
SolidWorks is another option but you have to pay for a hobbyist license.

I've recently switched from fusion to onshape.
Onshape runs in the browser which means you can switch between tablet and computer and desktop as needed. It's free for hobbyists as well.
The caveat to other free trials/applications is that the models are 100% open source/public (rather than the legal agreement that you cannot do commercial things in others while keeping the model private).
True! For onshape it's generally impossible to find if you don't give anything a descriptive name. But yes, the free version makes all of your designs open to anyone who can find it.
Autodesk doesn't do that. But you have the perpetual threat of maybe they will lock you out behind a paywall.
I have been learning Fusion for about a year, and gave Onshape a try a month or so ago. I just could not get the hang of it. I don't know why, but I really struggled and finally just went back to Fusion.
It takes a bit. It's missing some huge features related to parametric modeling where you can dimension on line and then click it to dimension others.
FYI Bambu labs is having their Black Friday sale until December

Well, isn't that just a kick in the yam pouch...was holding off on upgrading from my P1S to an X1C with AMS for many months now, hoping for a sale. Finally caved and purchased about 6 weeks ago...Murphy's a son-of-a-bitch...

I've been waiting for the sale for several months to buy one. I'm debating going with 2 AMS's.
I've been printing a lot lately with the Bambu X1 Carbon and it works great, though some filaments are more finicky than others. I mostly try to just use their filaments now and I seldom have any issues, but I've only been printing PLA and TPU.
I hope they have a little bit better sale soon, because I've been buying a lot of filament lately and for whatever reason I get some feed issues with their refills but not their spooled rolls and a few other brand filaments cause me issues.
The Bambu stuff is excellent though. I think most people that are interested in this stuff should get one of the enclosed Bambu printers, I don't think the touchscreen is all that useful, but for me connectivity is HUGE. I often make files in Solidworks on my work computer and then send a stl file to my personal laptop and I can print from work and checkup on the progress and kill the print if something goes wacky. However you do need some sort of drawing ability because 90% of the useful prints are going to be custom stuff unless you're more into the toys and ornamental type stuff. There's still some nice scalable drawings out there, but to really 3D print you need to be measure, scanning and experimenting for custom applications.
I've been working on lot of organizing type stuff lately and it's incredibly useful. I need a lot of stuff to have a tight fit because I have a lot of mobile needs but this printer is really giving me some incredible flexibility to develop some really nice kit to work in conjunction with metal work or wood working or sewing, etc, there's times you just need something custom and plastic or rubbery.
If you're on the fence, these things work more like an appliance and I really think they're worth it compared to the cheaper ones. Everyone I know with the cheaper ones are pretty much fine with giving them away because they've either printed the few things that were easy and it's collecting dust or they were discouraged and spent more time working on the printer than their prints, but to each their own.

Yes get the hub and 2 AMS's. The AMS's are really cool. Definitely should get 1, but 2 would be better IMO if you can keep them filled with filament.
I've been thinking of stacking AMS's and I've seen some mods to use TPU in an AMS.
