The secret ingredient is crime
-
The first time I took on modelling a replacement part, I took as many measurements with a caliper as I could, fired up Fusion 360 and just went for it with no prior experience. It is actually really intuitive and all you need to do is visualize how simple shapes like circles and squares can be used to construct the object. Basically, don't be scared of starting out and try to break down the object into simple and approachable parts.
My first object was a kind of transmission cog, so a very cylindrical object, much like yours. All you really should need is the diameters of different "circles" comprising the model and the cylinder heights.
There are lots of things I would like to fabricate I just suck at 3D software. Fusion 360 easy?

I'm telling the missus that you think her kisses are only minor theft worthy!
At scale, it's a felony, I promise!

Both are appropriate responses to the bullshit that is oven knobs.

Could someone point me in the right direction to get started on projects like this? Specifically I have an old Emerson CRT that the volume/power knob is missing on and it's impossible to find an OEM replacement. I've been dreaming about getting into 3D printing to print my own, but I don't know where to even begin considering I would need the exact dimensions of the D shaft and then to model something. Appreciate any help, thank you in advance
Get yourself some cheap calipers, radius measure, etc from Amazon. You don't need to spend a million dollars for some basic instruments. This will help you measure things you find in the real world.
For CAD, if you want a really easy on-ramp, try using "Tinkercad". They have a free option for users and there are lots of people who have made really usable replacement parts for things. If you end up really liking it, there are more powerful and complex CAD programs out there, but this will get you a friendly start without spending a lot of money.
If you have problems on the printer end, you can export your Tinkercad projects and send them to "Shapeways" (or other vendors) who will take your CAD file and return a 3D print in the mail. You can also buy your own 3D printer if you wish.
That should get you started, and if you pull all 3 of these threads, you will be able to start reproducing things around your house. Have fun!

While I don't do it myself, I don't consider stealing from big name stores theft and am, actually, completely morally fine with it. Will not report somebody stealing even if I see them.
The day big corporations stop stealing from the workers is the day I care about stealing from them. That day will not come.

Let's not forget the rampant wage theft across the entirety of the US, much less the ongoing grift they're pulling on its citizens re: "shoplifting", etc. being the big scary Evil — when wage theft stats completely destroy the charts in comparison to all other commercial/consumer theft, including misappropriation by employees!
TL;DR: Stealing from big corps isn't theft. It's a civic duty, at this point.

wrote last edited by [email protected]To me it became easy once I realized that Fusion 360 is not Blender. You're not sculpting a model. You're essentially just writing mathematical equations ("constraints" in CAD lingo) that produce the desired 3D object. For example, let's have a flat circle as a base with diameter x, then we extend it into the third dimension with length y, and so on. Once I realized how it works, it became much clearer to me what to do, because I literally just need to express my goal to the computer et voilà. I'm having a difficult time translating what I mean into words, but perhaps you can remember doing some kinds of geometric constructions in elementary school like a perpendicular line through the middle of another line. That's exactly what CAD feels like to me.

That’s very clear, thanks. I’ve done some before but only in Google Sketchup which in my opinion is incredible, and a shame it’s not available on more platforms for free. Anyway thanks it sounds pretty straightforward.
I know there’s also something free online that’s a web-based creator; I forget at the moment which it is but it looked pretty easy.
Thanks, I appreciate your response.

Back in the day, that was solved with a vice grips. This is because vice grips are the wrong tool for everything, but the right tool for not having to go find the right tool.
I use needle nose multiple times a week in this TV! Haha

Honestly, if you only have that one specific application in mind, might be more cost/time-effective for you to pay someone else to 3D print/ship the part for you, instead of getting into all that yourself just for the one use case.
I've had that thought too, but I'm a tinkerer and I dream of printing parts for my random protects. I appreciate the suggestion though!

There's https://lemmy.world/c/3dprinting where you could get more answers. The yt channel TeachingTech has some good series on getting into various parts of it (basics of printing, part design, machine maintenance, etc.). There are many other resources.
I appreciate the links! I'll do some learning

Once you have a printer, there are repositories online with models for just about anything. I've used Printables, and Thingiverse is another option. Someone may have already solved your problem by posting a usable model, just need to print your own part. Otherwise you can design one. Been using Solid Edge from Siemens, they have a free version for makers. Also used FreeCAD in the past, which worked, but wasn't happy with it. It now has a 1.0 release though, so probably worth trying out. They're going to require spending some hours learning to do designs properly, but once you figure it out you can sketch up all kinds of great things. I love being able to send my parts through the slicer software, then over to the printer, and out comes what I want. Learning CAD, or modeling software like Blender, gives you a lot more options with your printer.
Appreciate the info, I'm stoked to start learning!

This sounds like a great path for me, I love driving in head first. I appreciate you!

9k? That's a major city. I lived and worked in an area where the 9k town about an hour away was the bee's knees for the folks where I was, which had a great!!! city of 2,500, and the rest were unincorporated places of a hundred or so at the crossroads.
Shoot, I just moved to town under 1k.

That link doesn’t load for me? I’m really interested in what you designed. I tried turning my WiFi off and use cellar in case my pihole was interfering but that didn’t load either. Any chance the link formatting got messed up or something?

Not sure why it's not working for you. I tried it with a couple of browsers in incognito mode and it works fine for me.

I recently re-did my kitchen floor with 1' square peel-and-stick vinyl tiles. After buying four boxes (30 tiles each at $45 a pop), I ended up exactly one tile short. I was sorely tempted to go back to Home Despot and slip one tile out of a box - obviously people do this a lot there since there are always open boxes in the tile section. In the end I just pieced the last tile out of scrap bits, in a spot where it really wasn't obvious. I don't need a fucking shoplifting charge at this stage of my life.

Oh, are we confessing to
minorthefts? Let's see, what's beyond 7 years old...A Hogwarts robe clip from a Halloween costume
$12 in expired powerbars
About $200 in assorted mediocre liquor from some wedding
4 posters from bus stops for the Scooby-Doo movie
A 1999 Ford Explorer
7 Playboys and a bag of old coins
97 million kisses from my missus
(Edit: the largest thefts are the kisses)
I used to shoplift handheld electronic games, stuff like Electronic Quarterback by Coleco. I was a paper boy and I would walk into stores with my bag around my shoulder and just grab games off the counter and slip them in the bag. What blows my mind now is that this was even possible - this was the late 1970s and apparently I was something of an innovator because the stores never suspected anything or searched kids, and the electronic games were just sitting out on counters. It wasn't long after this that stores started only allowing two kids into the store at a time and shit like that, and searching them when they left.
You're welcome, subsequent generations of would-be shoplifters! You'll never know just how fucking easy we had it.

Taking from e-waste dump isn’t a crime it’s quite the opposite. If you can make use of it instead of it poisoning the ground, kudos!
crimes don't care about "ethics"

My secret trick?
I've been using the same stove for a quarter of a century. Was here when I moved in.
The trick is: the knobs don't come off. (In the extremely unlikely chance they might come off, I, like, just put 'em back in. I guess. Not that it happens!)
Looks like they don't build them like they used to!
Kids today just don't know the joys of sticking paperclips into the knob-less posts and then trying to guess what each stop on the knob does.

I'm so glad I learned THEFT
I know right? They need to teach it in schools!
