So my colleague printed up just the body for me, it took approximately 3 hrs @ 60% density for PLA Filament. He said he would print up another one, but I told him to hold off so that I can get the latest chip and start modifying the original files to the spec I want. Does anyone know if there is a way to get *.OBJs or *.SLDs from thingiverse? When we imported the .STL into SolidWorks, we had a bunch of triangles, because it seems whatever program the creator utilized, it was in high poly mode on export. I could manually edit the topo, but "ain't nobody got time fah dat!"

Even @ 60% density the thing is still pretty strong. If I where able to modify the file for the newer chipsets, I would give it back to the community.

Just wondering if the creator would release an OBJ, if not I mean if I really had to I can re-topo the triangles out, get poly quads, make the changes to the design that would fit the chip and re-release it.

From the import we did of the STL into SolidWorks it seemed plausible, only in the cutouts where there major triangulating issues and in some supporting edges, so it wouldn't be too difficult to modify it. I would even make it slightly larger to fit a better bottle in, since the discussions have mostly revolved around bottle sizes fitting in.

As far as I know there is much information lost in conversion. Much the same as taking compiled code and wanting the original code.
Yeah I understand that concept since in another lifetime before I became a software engineer, I spent a lot of time and money learning cg technologies in the form of high/low poly surface modeling, technical animation, lighting, and rendering.

I have successfully reverse engineered 3d models before, but it requires an extensive amount of time and quite a bit of knowledge in regards to quad polygonal edge flow. I can do it, its just the amount of time it takes. Here's an example from my demo reel I made from my first go at college.

They make reversal tools for that.
Disassemblers only go so far, and if the code was obfuscated not very far at all. Most of my past reverse engineering was done on very specific sections of code using a debugger in an emulator to stop execution and single step through watching registers, where the code was jumping, memory locations, and any IO going on to figure out how to make it do what I wanted it to instead of trying to get back to original code. Most access codes and passwords are meaningless with as little as 1 jump statement changed unless there is a checksum involves.

Yeah I try to avoid that as much as possible, nowadays I'm typically in automation and user space so I'm not that low-level. I have done it recently for a class and would not want to deal with stepping through registers and watching memory locations. I work in virtualization, specifically storage virtualization.

So just got home a little bit ago from work and was able to do this real quickly with some Reo parts I had laying around. One time I accidentally ordered a 3.5ml bottle for a reo mini I believe. Looks like I can put it to work for now. Have a couple extre BeCU springs laying around, that'll work. Tried test fitting the super monster bottle from the CC and it wouldn't fit or the standard Reo bottle. If I added 1.5~2mm to the left it should fit in fine, a little tight to the battery but not too bad.

Starting to get ideas, any suggestions welcome. Think I'll add 1.5~2mm to the left, then create another wall that will contain the battery in its own little space, that way juice will hopefully never touch the battery.

Looks good. I'm still bottle-less and don't want to commit to those square Japanese bottles until @sheerlucksherlock is done experimenting with the Reo bottles. 2mm wider and this would be a great enclosure. Along with keystone contact holders built into the enclosure instead of screwing with springs. Also the Italian guy that designed it says he swapped the sx350j wiring with 16awg silicone but I don't want to do that because yihi is horrible with warranty and as soon as I touch the board with a soldering iron it's voided

Trig identities....proving them was one of my least favorite math things....in fact any proofs. I figured if someone else proved them already just give me the facts to run with. Thank goodness that was 35 years ago. Come to think of it I've never had to prove math (except the kids, nephew, and niece's homework) since college.

Trig turns out to be the only maths i was taught that has had any practical use in daily life since i left education.

Algebraic long division i always considered to be a waste of time and still have no idea what use it is.

The benefit i see of a spring over a keystone holder is that it's easier to replace and affords some protection if you have a short.

Yeah trig identities are tough, having to go back to school after my BS in Computer Animation as the job want's me to get more formal training. So since I went to private school (credits do not xfer), had to go back to my public school AA to get started for the CE/CS double major I'm doing. My first degree only required up to College Algebra, after 12 years of not doing college level math decided to re-take College Algebra and then go Pre-calc seperately. Now I'm finishing up Trig, got Calc 1-3, physics for CS, and discrete mathematics left then I transfer from College to University. When I finish I'll have 3 friggin' Bachelors. I'm 31 almost 32 now, married, and we just purchased our own condo, guess I'll be finished with school sometime in my 40's, if I go Masters/PhD route, probably longer lolol.

Been in the Software industry 5 yrs now, started as an intern running cable and deploying development/test environments, did some documentation, made test plans, went QA, then did automation via PowerShell and Bash/Shell scripting, and now finally I'm a Software Engineer I working in C#, PowerShell, C++, and some C. The QA has actually helped a lot, doing QA for 2.5 years has really taught me some stuff to look for in Programming. Do I miss computer animation? Sure, but since all the jobs got outsourced, I didn't want to move after every project, not have benefits, and work 120+ hrs a week. Right now I work 50 at my day job, got school, and can manage a freelance wedding photography business.

Yeah I'm finding Trig to be very useful for a lot of applications, we shall see how I fair in Calc, Pre-calc was a nightmare for me. Could have been because I had family members getting sick left and right or that I hadn't really done college level math for 12 years. Pre-Calc was super hard, luckily I got a B, but that B was probably more because I went to every single class, did every single extra credit, and I was always asking Professor for help and asking questions when he opened them up during lecture, probably should have gotten a C.

When i was at university i shared a flat with a Greek guy* who was a mathematician and the world record holder at Ouzo drinking. He was 33 and very hairy.

i do not miss the days of studying, but i never served an apprenticeship so i have no plumbing expertise. I'm barely able to use a computer, so of course my job is to work on them all day. By 11 o'clock when i have managed to boot the bloody thing, i begin my work.

My days are long.

@sheerlucksherlock
No luck with finding a bottle other than those square Japanese ones and I done need 100 of them lol
Do you know if the 6ml Rio bottle will fit?
The bottle, I tried ordering, wasn't 16mm. It was the same size as a Reo bottle. I shaved a couple mm off the walls, of the case, where the bottle sets. I used a Dremel tool and an Xacto knife. I got the Reo bottle to fit with the battery and when pulling the battery out it barely rubs the bottle. I'll probably shave off a little more and try to get it frictionless.

So the 6ml Reo?
If you modify the bottle space only. The front door and/or the back of the case need to be shaved, to get the door to fit flush. The bottle will squeeze in from side to side, but its too tight in my opinion. You might want to give you're Japanese bottles a try?
