Thingiverse

The other day in class, we really got into the thingiverse website and everything it has to offer. Almost anything imaginable is on the website. The great thing about the site is anything that is on it is open for the public to change for themselves or even print the object out as it is. After looking through the website, there are objects that appeal to my interests and also objects that make me wonder why anyone would design it.

Above, is a bust of batman that was on thingiverse. All objects can be printed in any color. It just depends what you want and as you can tell, the person that printed this batman bust wanted it in a stunning green. To me, this bust is an expression of art. Obviously the creator of the bust is not just tech savvy but also into comics. This comically work of art can be displayed in your house as a center piece or even as a conversation piece. This piece is artistic to me because it relates how passionate the creator is about comics as well as their technical skills. According to thingiverse, 38 people have printed this bust. However, as the creator states, this object is made for personal use only and not for profits.(thing 241,899)

The next object that i found was a tool holder^. After looking through the multiple pictures of the design, i thought it would be very useful to many people. Not only can this be used for tools, but also any kind of odds and ends laying around. For me however, i would enjoy using this in my garage for exactly what the creator says, for nuts and bolts. My collection of nuts and bolts is absolutely out of this world and i currently own nothing to organize them. This object however could change that problem in a matter of minutes. Five of these organizers have been made to date. By the looks of the design, i believe this object was designed for manufacture simply due to the reason it's multi-functional, therefore having a broad market.(thing 14,493)

 Since my mind was on tools, i decided to see if anyone would actually think to make tools out of plastic. My next object above is simply a adjustable wrench that i found on thingiverse. To me, even though it looks great, is the most useless design that i came across. I say this because  wrenches take a beating and also have to hold up under pressure as well as getting hit by hammers to loosin' bolts. Obviously a plastic wrench would be nothing more than a show piece, but then again who wants a wrench as their show piece? As it should, there are no prints of this object and it was not made for manufacture because it simply wouldn't work the way it should.(thing 455,670)

I came across this Draco dragon miniature sculpture browsing through the newly added pages. As soon as it came on the page it instantly caught my eye. At first i didn't know what it was and then when i clicked on it, i was even more confused by it. I starred at it for a few minutes looking at all it's curves and details. Objects don't get much more bizarre than a mini Draco sculpture which looks like a long horn sheep from hell. Currently, there have been 4 prints of this object and i believe that it wasn't made for manufacture because it simply has no purpose to the average person.(thing 185,305)

, Being the car savvy person i am, when i was searching engines, this small inline 4 cylinder model popped up. This model includes quiet a bit for being what it is. It has the pistons, connecting rods, all connected to the crank which is turn-able, which is all situated in the block. I would enjoy having this piece or making this piece because it is small enough for it to be on my key chain. Also i could use it for daily demonstrations when people don't know how a simple engine works. Plus, it's just a cool and unique piece that could be fun to play with when I'm bored. Out of all of the objects I've presented, this one has the most makes totaling 10. However, like most of the others, I don't believe this object was designed for manufacture, but instead for made out of curiosity and being a car lover at heart.(thing 10,761)

Poor Design

Most recently, the poorest design I've noticed and experienced was on my 1987 Mitsubishi Starion. This car was built in the time period where car manufacturers were switching to computer systems for cars instead of all mechanical components. Also, in this time period fuel injection was designed. Fuel injection helps better and more accurate fuel flow into the intake system of the head of your engine. With fuel injection, it takes out the manual adjustments and the computer tells how much fuel each injector needs to flow into the head. The computer is also hooked up to a MAF sensor which reads how much air is coming in and how much air is appropriate for how the car is running. Prior to fuel injection was the carburetor. The carburetor was a good system that many could learn how to adjust on there own. In a carburetor, there are a few main parts. You have the throttle body/plate, jets, and adjusting screws. The throttle body is opened, which moves the plate vertically open. Air comes through the opening and is mixed with the gas that the jet is set to push out depending on the settings of the adjusting screws. The adjusting screws are there so if you want to make more power, you add more fuel, and you can just turn the screws to a setting that works well for your setup.

However, Mitsubishi decided to say piss on this all new setup, lets make our own. Mitsubishi went with a setup known as MPI or multiport fuel injection. Also, with MPI, Mitsubishi used two injectors, a primary and a secondary, instead of an injector for each cylinder. The way the primary works is it runs all the time at full operating cycle. After approximately 3000rpms, when the turbo registers boost, the secondary injector turns on and works at full operating cycle until the engine is no longer running in boost. Once the car is back into vacuum, the secondary injectors stops working and puts the full load on the primary injector. Also, the way the secondary injector reads how the car is in boost is by a jumbled mess of vacuum hoses and everyone knows that one tiny hole or loose gap can cause major problems. By not having the injectors in an intake manifold and just setting in jet carbs, there is a long gap between where the fuel reaches the head to where it comes out of the injector and through the carburetor. This causes lag, which is a huge problem. The second you step on the pedal you want to shit and get, but with this setup you stomp on it and it feels like your just sitting still until a second later when the power throws you into your seat.

To fix these problems, My brother and I did a direct port injection swap. In doing so, we took the old intake manifold, fuel system, and cylinder head off. Afterwards, we installed an aftermarket intake manifold onto a b2600 head equipped and ready for direct port injection. Once on the car, we ran new feed lines to and from the gas tank connected to a fuel pressure regulator which is ran to the new FOUR injectors. Thanks to SAFC tuning and logging, we were able to add more air to the tune and start it right up. Proceeding that, we fully road tuned it over the course of the next week. With the new fuel and intake setup, and a bigger turbo I threw on for shits and giggles, I was able to over come the terrible designs Mitsubishi had made in 1987.

About Myself

Hello everyone, my name is Justin Geedey. I am currently second semester standing at The Pennsylvania State University in State College, PA. Prior to coming to the State College area, I was born and raised in a small town called Selinsgrove, PA, which is approximately an hour east of State College. Growing up as a child, I was always very close with my brother and father. I constantly found myself always tagging along, usually to the local hardware store or auto shop. As long as I can remember, I was always working on some kind of project, may it be helping my father build the house deck or pulling engines apart and swapping heads on my brothers car. So, when deciding on what I want to go to college for I sat down and tried to recollect what I loved to do as I grew up. The biggest words that got stuck in my head were building and design. At that point I knew I wanted to study engineering. I applied to Penn State not only for their outstanding engineering program, but also because my mother went to Penn State when she was younger and now currently my brother attends the university as well. After a single semester, I can tell I won't have a problem being here four short years.

If anyone would like to get to know me better on a personal level, just know that I'm a car nerd that loves to golf as well. In high school I was two time runner up in districts and a two time regional qualifier. However, I'm outgoing and willing to try just about anything, so say hi sometime.
