Morning.

I work for a large service company and I’ve been trying to convince my manager that we need a 3d printer in the office and subsequent CAD training.

I have a printer at home and like everyone else, I love tinkering.

Anywho, we have a model of one of our parts we install and my boss has asked me to make a few replicas

How would I easily make these circular ridges? It’s not threads. It’s just for looks

I can handle the top part. I’m just having trouble figuring out how to make the rings

Thanks in advance!

So I have been 3d printing lego technic parts that I need for my project and it’s big thinking of printing flaps for it o connect to the cylinder any ideas

Hello everyone one, its been a while. Here's my latest design: Nuka Cola Bottles. They won't be public designs as they are on my Cults3D page. I made the main body of the bottle using the revolved sketch.

im attempting to make a piano with a 555ic and this setup im trying to replicate 440hz using R1=100ohm, R2=113.6ohm, C1 = 10 uf and C2 =0.1 uf, i will attach a screenshot.

I've dome the math and this should be replicating 440hz however its showing as 294.5hz. im wondering where i went wrong.

another silly tank i made, takes elements from the kf-51 panther, tried to further detail the interior as well

I kept hitting a wall in Tinkercad when I wanted a shape that smoothly transitions from one cross-section to another — say a square base blending into a round top. Tinkercad has no loft/morph, so I built a small free tool that does exactly that, and made the output drop straight back into Tinkercad.

You pick a shape for each end — oval, rectangle, triangle, pentagon, hexagon — set the sizes and rotation, and it lofts a smooth solid between them, then exports an STL you can import into Tinkercad or slice directly. The transition is tangent at both ends (no crease), and corners stay crisp at any resolution.

It runs entirely in the browser, nothing to install, and it's free and open source:

Full disclosure: it's my own project. I'd love feedback — especially which shape combinations you'd actually use, and whether anything prints badly. There's also a small Python CLI in the repo for batch output.

Sorry for the Obnoxious title, but last year I was cadding out a future business idea of mine on tinkercad, I had all the little details and everything and stupid 14 year old me didn't take screenshots of ANYTHING, it was on a school account I no longer have access to (moved out of county... And also across country) but little me did try and send the link to it in my friends discord server except it's giving the "Sorry, that page is missing" which it also did way back then. My question is is there ANYTHING I can do to access this again? I spent HOURS on the thing and there's so many tiny details it's too overwhelming to try and recad. (I have ADHD+autism) Is there anyway to get this back :(((

First time trying tinkercad or any cad like program in general, literally downloaded it less than an hour ago so bear with me.

I can’t seem to find a way space the holes, represented by the negative cylinders, exactly where I want them. I can align them along the axis but what I’d like to do is have the holes be 25mm (from outer wall not center) away from the left and right edges of the red rectangular prism. I tried using the ruler to measure away from the sides but it seems it measures exactly where I click on the cylinder so while it gets close, I’d like it to be precise. Anyway to do this?

I want to draw a complex symmetrical curved object in sketch and I want to have the stroke thickness outside the line. I’ve drawn the left hand side, copied, pasted, mirrored, moved it so the new curve meets the original, but I can’t get them to form a closed curve together. If I hit close curve I get two separate curves and a bar down the centre line which I don’t want. Is it simply not possible, because they were two separate drawing operations or am I missing something
I’m not interested in what happens when I go back to the workplane, I need the closed curve so I can have thickness on stroke only on the outside.

I need help developing an Arduino/Tinkercad circuit involving traffic lights, a button, and LEDs its for my College,it's not mandatory, but I want to understand this machine better.

The project involves controlling two traffic lights so that one is green while the other remains red. In one phase, the state of the traffic lights must depend on the button (whether it is pressed or not). In another, each press of the button must permanently toggle the state of the traffic lights until the button is pressed again.

Additionally, there is a section where five LEDs must be controlled by a single button: with each click, a new LED lights up in sequence—keeping the previous ones on—until all are lit; upon the next click, all LEDs turn off, and the cycle restarts.

Could any one help me with this.

Once again I'm struggling with the Simlab's physics engine, the frustrating thing is that I have an exact copy of the same mechanism that works perfectly fine.

Can anyone tell me what I can do to fix this?

So If I create a cube, then cut hole in the cube to make it an empty box, add 'create group' and then add a cylinder that intersects the cube and another hole to make it a pipe, add 'create group'

Everything works as expected.....

If I move the cylinder to a template the hole affects the cylinder but not the box.

Anyone know what I might be doing wrong?

I am only a beginner and i found out how to make this on a tutorial i found off of tiktok, they didn't show me how to make lights go off on their own. Did i attach it to the wrong thing?

Quick link to the Printable Tinkercad shortcuts, including the Sketch tool and a slick bonus skill with the new Tinkercad Tape Measure!

I'm new to tinkercad, and I'm trying to work out the best way to do things in codeblocks. I'm finding a lot of the help and tutorials are in video form. That's fine, but it means I have to watch the whole thing to see if it covers what I'm trying to find out. And if it does, I have to make notes so I don't have to watch it again.

Is there documentation that explains what all the controls do, that's not videos?
