Q: Do you know what they call an engineer at graduation with a C average?

A: An engineer.

[Anonymous No.2807393]

Well yeah, your teacher is right. It is pathetic. If your instructor looked inside, you may have lost more points. The internals are nothing to be proud of. You have loose components and subassemblies and no thought for wire management. You have also learned the value of early prototyping which could have let you know your initial case was either too complex for your process or give you enough time to fix your process. It's also why EE and ME are different disciplines, because why would you spend time working on a mechanical design concurrent with an electronics design in the real world? Half-assing a complex design is going to be far less robust than carefully and correctly executing a simple one. Take this lesson and improve your skills in the future. A lot of the time you can optimize speed, robustness, and cost by reducing complexity as early as possible.

No offense OP, but you're at a UNIVERSITY, go out, MAKE FRIENDS, and you can probably get a case design for a case of beer or a bit of something else.

You know why you fucked up? Because you used the wrong tool (3D printer) for the job (making rectangular body with even-thickness walls). There are pre made cases, if you need a bunch of non round holes or an engraving on the lid, you still buy a case but toss the lid and have a new one laser cut out of PMMA. It’s cheaper, stronger, scalable and more fault tolerant (redoing one with a decent cutter takes 60 seconds and $0.5 of material).

You will never ever see 3D printed cases or panels outside of hobby electronics for this reason.

[Anonymous No.2807457]

>>2807361
Looks to me like you threw some stuff together from ali express and called it a day.

Anyway, you could have made the case by gluing 5 panels together similar to the face panel in about 5 minutes.
Printing cases with a 3d printer is hilarious.
It takes a long time, costs more than a purchased ready-made case, looks ugly, and melts at 60℃. PLA is one (small) step up from hot glue or wax.
You would have been better off going to a recycler or second hand store and buying some small junked electrical device and replacing the front panel, and get bonus points for eco-friendly development from your obviously trans teacher.

>thinking about the circuitry for 20 hours
You strung together a small handful of pre-built components. 20 hours of "thought," and that's what you come up with? You didn't even do any management of all those improperly sized wires.

>no time to create windows for components that need to be visible me cut hole and not clean edges

You learned something today, so you were successful.
And the lesson is that technology is the prerequisite. People will just assume it works as intended (and be extremeley pissed off if it doesn't). So yes, technology is important. But what people pay money for is the package. Mediocre technology with a nice ad sold by a pretty girl will be more successful than excellent technology sold by a nerd with a cardboard sign for an ad.
So team up with someone sales oriented and you have got a winning team.

>The 3d printer fucked up
Your responsibility. Either your model was shit, or you didn't maintain the printer properly, or you made some other error.
>Have to print a shit case because you only have 5h left?
Why the fuck would you go so close to the deadline. This is entirely on you for having bad time management.
>My future work isn't to create cases
You'll learn the hard way that no matter how autistically technical your area of expertise is, presentation still matters and will influence how satisfied your clients will be.

See it positively: If what you claimed was true, you learned a lot in the process and made a good power supply circuit, the experience of which will help you later. You also learned more about the importance of soft skills, which might help you later in life.

If i were your teacher i would have fucking begged the higherups to expel you for being so dysfunctional.
I wouldn't even care about the 3D printing part, despite me specializing in this, because these fucking nuts and the cricuitry floating on wires just overshadow everything else.
Your case is not bad because it's printed bad (Though that is too), but because the design is absolutely retarded. I'm certain that if you at least had the whole setup look tidy you would have a way better grade despite the print fuckup.
>But muh deadline
First of all - your fault, second of all - you could have used normal screws since those can easily cut their own thread through most plastics, which is more than enough for a prototype.
>But it's not muh job to--
It says right fucking there in your major: "Designer for radio equipment". It's your job to put at least some thought into the case being good, since even if you aren't going to model it (Which you fucking will have to, one reason or another), you will still have to greenlight the decisions of someone who will, which requires knowing how to design a case as well as the electronics for it.

You couldn't tear apart something from the thrift store or your closet and stuff your project in it?

>9th grade physics, assignment: build a mousetrap
Was planning on an electronic trap with servo motors. Literally waited until the last minute and made a squirrel trap from a coffee can I remember my dad and brother making when I was like 4 years old. Got an A for "creativity" and because it worked reliably.
>10th or 11th grade chemistry, build a model of an atom, literally got fucking vanadium, I swear to christ I will never forget how many particles this atom contains
Wanted to make a 2.5D model with hobby foam. Waited until the two days beforehand and spent a mad all-nighter spray painting a bunch of used golfballs, and bolting every one in place with a drill and allthread. Got an A.
>freshman college spanish, make a poster or powerpoint with members of your family and give a presentation in spanish
Waited until the day before, cut up some MDF and screwed it together with hinges so it folded out and literally memorized every sentence with no actual understanding of what I was supposed to be learning. Got an A and an actual "what the fuck" from my baddy German hipster spanish professor.
>freshman college fine arts appreciation, open-ended project
Made roses from allthread, pipe caps, and a bunch of razor blades I epoxied together into petals and jammed them in one of my stepmom's vases with some of her roses from the garden, all literal hours before class. Got an A.

Great for me. The teacher was so incompetent at giving instructions most didnt even have anything to show and failed. I only painted the truck a pretty red and talked about what it could('nt) do.

Based on how many hours you put into this, did it you ever ask yourself how much time everyone else is pouring into this useless project for a grade?

In any decent school they will teach you something different which is a good lesson for career as well:
Nobody cares how much effort you put in, how much books you read about it or how ‘elegant’ your result is. It should just do what it needs to and be attractive. It shouldn’t necessarily do what the specification said it should do, it should do what the specification actually wanted to say.

The skill of the engineer is to read and decipher the specification, interpet it with his own knowledge, and make a result that works for the client.
