Need some advice on scanning (sh.itjust.works)

I’m having a bit of a hard time with this, but I also acknowledge this is still relatively niche still.

I’d like to make printed recreations of some parts that I currently have. They’re unfortunately a bit complex to quickly recreate manually in a sculpting software. I do have an iPad PRo and a budget for any additional hardware to help. I was hoping I could find a carousel I could connect to the iPad Pro and use and app to control the carousel and scan the parts. I’m not finding anything.

Can anyone recommend a good setup to make 3D scans of these small parts, or an app/hardware combo that could help me accomplish this?

You could look into an opensource project like https://en.openscan.eu/ depending on how "small" these parts actually are.

It requires some initial printing as well as some hardware kit purchases (provided) for the servo and controller board, but I saw a demo on youtube once that provided surprisingly good point cloud accuracy from one of these OpenScan pedestals. Good enough that you could probably generate smooth surfaces from them and make a usable part with minimal model post processing. And definitely better than you'll ever get from a freehand smartphone/iPad scan.

This could definitely work! I could likely get the parts needed printed at the library or local college! Thanks!

Glad to help! Let us know what kind of results you get. I've been meaning to buy one of these kits myself for ages but haven't had time to dive into it yet.

Regardless of the scanner use matting spray. Either a commercial that evaporates or baby powder + IPA or baking powder.

OpenScan was already meantioned by somebody else.

The CR scan otter won't work for small parts and the CR-scan software isn't great for example there isn't an undo button to remove the last x seconds of bad scan data.

Thanks for the advice! Shame about the CR, but the OpenScan would be more in line with my goal of using my existing equipment. Thanks! I’ll be sure to get some of that spray too!
