L5 Riesig Battlewalker from battlefield 2142 by Humungotron

Last crawled date: 3 years ago

I'd spent untold countless hours playing Battlefield 2142 back in the day, and was always fascinated with the walkers. Who doesn't want to run around shooting bad guys with a giant robot?
Using all the reference pics I could find, as well as some images of a well-made fan model (sadly, his image is available via google, but it looks like Sadguyd8's DeviantArt page is down at the moment) and a pepakura file I've had floating around my hard drive for years - (available here https://goo.gl/N1iSji ) I decided to build one, using Fusion360 to model it. I tried to keep as close to the original as I could, both in scaling and shape, but some parts of it have been smoothed out to be a little more realistic, at least in my opinion.
The top turret, mini-guns, upper to lower torso joint, and legs are all movable/posable. all the part interactions are modeled at a .2mm gap, so if your tolerances are off, it may end up being a static display.My printer isn't super tuned, but I can get decent prints out of it, and had no issues with fitting things together. Also, this thing is large! the upper torso measures 91/2 long. Smaller printers will probably need to have some parts re-split. If it's needed, leave a message and I'll upload them when I can.
This is still a work in progress, but is mostly complete. As i sit down and write this, I'm in the process of printing the lower half of the legs. As such, everything above that is printable, and I'll modify and update if I run into any issues in the interim.
As a side note, I chose not to print the barrels of the two mini-guns. I used 2mm OD aluminum tubing I'd purchased from a local hobby shop. Enough tubing to complete both mini-guns was approx $3 US. each barrel is 64mm in length, which I cut using a hobby saw blade for my X-acto without problems. I have not included a printable barrel, but again, its something I can add if someone wants it.
I've also included a .zip file with all the parts, broken down by what goes where. I find it makes it a lot easier to print multi-part files, hopefully you do too.
UPDATE!: I've re-uploaded the parts at the correct sizing. Its currently 400% of the originally uploaded size. If you have an SLA printer, you could probably get away with the smaller size, but I'm not that cool :p
I've also broken the top turret into easier to print parts, and separated out some parts of the main body and lower torso. The legs are working, I have finished the left leg, and have the right leg printed, it just needs cleanup and assembly. I may do some more modification on the foot, as the shield currently hits on the lower leg when swung fully forward, and I'd like to be able to change the mount of the shield to prevent this. I also intend on adding some 'snap-stops' to the knee and lower leg, allowing it to be posed like an action figure. I have them modeled in the torso to upper leg, and they work correctly. Without adding them to the other parts of the leg though, they don't hold position well, especially with the main body weight on them. As is, its currently completely printable, but there are some modifications I'd like to make to increase its 'posability'. I'll upload pics as soon as I've finished assembly, which will be in a couple days (work calls, and I don't have a lot of free time when I'm working).
UPDATE 2!: Its finished, and fully printable. I'll update the legs at some point in the future to be posable. For now, you'll need to glue them. I was hoping a friction fit would be enough to hold a pose, but the weight of the upper body is too much, and it ends up sagging into 'park'. I'll need to make some significant modifications to get this to work correctly, but for now, it makes a decent (and HUGE) static display/model. I've learned a ton doing this, and I'll keep fine tuning it as I learn more.
Update 3: Cleaned up the zip file, per sappy234's recommendation. Thingiverse is being a little picky today, otherwise I'd remove all the individual files. The zip is organized by body part, making printing and assembly a little easier.
