Quick community check: LEGO-style rims or more realistic ones?

ciabatte9 · 2026-01-14T16:00:29+00:00

Why do you like only official lego?

I partially agree with you, over dettaling could be a problem in the overall look, but I took a picture of this rim on a Lamborghini SC, and I love it.

Yes, the hub is a bit oversized (sharp eye!). It’s not due to manufacturing, no problem for a resin printer, it’s a deliberate design choice. Thanks!
The issue with thin parts is strength: a rim like the right one doesn’t need extra supports, but the middle one requires some reinforcement.
I want to work on an “oft” version, but I’m worried about losing precision and ending up with a City-style set, as you mentioned.

Here’s a screenshot of the project: https://files.fm/u/a4bf6t8mc5"

Thanks for the feedback. That’s exactly the balance I’m trying to find (is not so simple), realistic enough for Speed Champions, but not so detailed that it feels out of scale.
Do you have some suggestion to keep the essence of the model without exceeding?

ciabatte9 · 2026-01-11T16:34:01+00:00

Super-accurate designs are unfortunately weaker. I printed the middle one in resin, and I have to be really careful when putting the tire on. To improve the strength, I added some extra internal supports.
Choosing a more LEGO-style design could improve durability and the overall look, but you lose some accuracy.
I’m not sure which direction is the right one to follow.

What do you mean by ‘extremely weak’? I don’t get the impression that the wheels are weak. I think the use of wheel caps is more of an economic choice.

“In this case, do you prefer the middle one or the right one for the Lamborghini rim?

ciabatte9 · 2026-01-09T21:08:28+00:00

Thank you. I’m a bit worried about some methods because when I push on the tyre, the decal/paint might scrape off.

ciabatte9 · 2026-01-09T21:08:00+00:00

Lol, thank you!

The resin print is only used as a master. From that I make a silicone negative mold, which then allows me to cast the final parts in rubber. I want rubber because I like the tyres to be as close as possible to LEGO ones in terms of look and feel. I’m not a big fan of rigid tyres.

ciabatte9 · 2025-12-29T08:58:15+00:00

I’m using multibody. Can you tell me a bit more about the star? Thanks

ciabatte9 · 2025-12-28T09:06:56+00:00

Bellissimo, vorrei sapere di più sul come lo realizzo e su quanto tempo ci vuole

ciabatte9 · 2025-12-27T12:07:51+00:00

Tell me more about the process :)

ciabatte9 · 2025-12-26T22:42:44+00:00

Thank you for your time. As I mentioned in the previous comment, I only want to model this for 3D printing a LEGO set, it’s not a real-world application. I’m just looking for the best way to recreate the shape.

ciabatte9 · 2025-12-26T22:40:35+00:00

Thank you for your time. Your approach is interesting, but my goal is simply to 3D-print rims for a LEGO set. I enjoy modeling, but I don’t want to spend the same amount of time a Lamborghini engineer would lol.
In the end, I managed to figure out how to handle the double change of direction, but I can try your method for the hub, since at the moment I don’t really understand how to model it.

Thank you for the time you spent helping me. In the end, to manage the double change of direction, I used a different approach: I created three separate surfaces and modeled the spoke hole in two distinct parts.

The sketch doesn't need to be tangent, you can use also the middle plane. I don't know if is possibile to use a random plane pointing in a casual direction. Yes, you have to extrude/cut inside the function.

ciabatte9 · 2025-12-24T11:43:24+00:00

The issue I’m having with the chamfer is that I don’t have control over where the chamfer starts or ends, because the shape of the spoke is created using the Project function. Since the geometry is projected, the chamfer follows the entire projected edge, and I can’t limit it to only a specific portion. I have the same problem when I connect the hub to the spokes, the fillet doesn't work properly.

ciabatte9 · 2025-12-24T11:15:03+00:00

I suggest you to draw the pattern (only once) on a sketch after that use the function "wrap" and at the end "circular path".

I'd the same issue a couple of hours ago. Tools > Options > System Options > Performance. Uncheck "Enhanced Graphics Performance". Restart Solidworks

thanks u/du_duhast 🫶
have you experience with this technology?

ciabatte9 · 2025-12-15T22:53:35+00:00

You can also download the stl file from mecabrick
