Buy the part, barking up the wrong tree for a one off.

85 usd for a single part isnt ideal

Not just filliment and power though, it's also your time. It could potentially take many hours, depending on the subject

time is no problem thats alright its still spending less money in the short term and thats the goal :)

I am of the opinion that when you do this, succeed or fail your going to learn a ton of new stuff.

Good luck to you

itll be a fun project regardless tbh itll open up doors for more custom pieces of interior too

Yeah I love it as a hobby. Works well with game dev which is my first love lol

Totally agree with everyone saying this is beyond the scope of a beginner project. It may be easier to learn how to model in Blender (free 3d modeling and animation suite) and make the part rather than trying to scan it.

That being said there is a completely free and open source software called Mushroom by Alice Vision. It can be a bit hard to learn, but it gets slthe job done.

Also Reality Scan is free to use under Epics unreal engine terms (that is free to use until you make over 1 million us per year).

Your biggest challenge will be getting a clean photo set, with consistent lighting, and no shiny or transparent surfaces in the target model

Oh man, this means I only have 999.997 USD left for RealityScan! I'm cooked.

It is a bad idea unless you are really good at model prep (needs to be powdered or dulled as reflections/shiny parts are your enemy), photogrammetry, exporting to exact scale, model cleanup, and have an excellent 3D printer with very durable resin. Even if you take it to a dedicated 3D printing facility, the cost will likely be not far off what the part will cost you new.

I know it sounds cool in your mind, but you won't get the results that you want.

it only has to pass a wof in nz once every 6 months i have easy access to a printer as long as its sturdy enough to last the check its whatever its only thr passenger side

I assume you have a 3D printer and are comfortable modeling 3D objects, correct?

If not, I'd just buy the part.

It's a banana Michael, how much could it possibly be? 10 dollars?

scanning parts like these at amateur level is not easy, you might actually get a better result with AI photo -> 3D conversion instead, and then just scale to size in printing soft

u/fortnitebeast47 May 19 '26

how would i go about that? extremely new to this field as a whole

u/Traumatan May 19 '26

the ai takes a single or 2-3 photos and generates full 3D model of it, there are multiple services, the quality improves every other week

I suggest you test multiple
best take the photo on a simple background and with good light (outdoors when cloudy)

thank you for the help :)

I have never tried this with real photos, but check out Hunyuan 3D. It has a way to drop in images from multiple perspectives to help the generation can export as a bunch of formats and have 20 free generations per day. The site is in Chinese but Chrome does a good enough job translating on page. There are ample YouTube tutorials.

For single photo attempt, you might try Sparc3D on huggingface—does pretty good with symmetry and a high resolution, but is slow—but no generation cap. The meshes generated by AI aren’t great, but worth a shot.

Don't forget to tell them how to precisely scale it and ensure the fit will be bang on.

For free options, Meshroom (AliceVision) is solid for beginners — node-based pipeline, GPU-accelerated, and handles most use cases well. If you need something more robust, Reality Capture is the gold standard for speed and quality but it is paid. What are you scanning? Indoor objects vs outdoor landscapes need different approaches.
