Has anyone successfully used a regulation-compliant 3D-printed part in prolonged contact with a cosmetic or food product?

I’m developing a small component that would remain in direct contact with a body-care cream for an extended period of time.

Because I’m currently testing the concept with a small number of units, I hoped to have the component 3D printed. This would allow me to test the design and make adjustments before investing in an injection mold for larger-scale production.

However, the more research I do, the more questions I have about material safety, porosity, bacterial growth, chemical compatibility, and whether a coating would be necessary. I’ve seen Chanel’s 3D-printed mascara brush and an example from another small body-care brand, but I haven’t found many products that remain in contact with a cosmetic formula or food for a prolonged period.

Has anyone worked on or seen a commercially sold product with a 3D-printed component that stays in contact with cosmetics, skin-care products, body-care products, or food?

How can I make this cover require a 180° twist before removal?

I’m designing a removable cover that sits on an existing base that holds a cream.

The underside of the cover has a raised feature that moves across the cream when rotated, which slightly mixes the top layer of the cream (this is necessary for this particular cream). I want customers to be required to rotate the cover approximately 180° before they can lift it out and access the cream.

The silicone base has already been manufactured and cannot be modified. The mechanism must therefore be incorporated entirely into the cover. Ideally, the cover would be one piece and suitable for 3D printing.
What type of shape or mechanism could create this twist-to-release action inside a smooth, circular base?

Has anyone seen a plastic part like this already on the market? (Food, cosmetic, packaging, or other industry)

I’m trying to find an existing plastic component that looks something like the attached sketch.

It’s basically:

* A flat circular plastic disc (~2.5 inches / 63.5 mm diameter)

* A single raised rib or fin on the underside that spans the entire diameter of the disc

I’m not trying to invent something new if this already exists. I’m hoping there’s an off-the-shelf part from another industry that I can adapt.

I’ve searched cosmetic packaging, peanut butter mixers, shaker bottle inserts, paint mixers, herb grinders, etc., but haven’t found anything quite like this.

Has anyone seen something similar in:

* Food processing
* Cosmetic packaging
* Pharmaceutical packaging
* Laboratory equipment
* Medical devices
* Industrial mixing
* Any other industry?

Has anyone seen a lid that agitates the surface of a thick product?

I’m trying to find an existing product or packaging component that will gently mix or refresh just the top layer of a thick cream when the customer opens the container.

My idea is something with short flanges, fins, spikes, spokes, or flexible ribs that lightly contacts only the surface of the product. As it’s twisted, it would smooth or gently agitate the top layer—not mix the entire container.

It doesn’t necessarily have to be attached to the lid. It could also be a separate insert that sits on top of the cream, ideally disposable, with a small tab or handle that sticks up so the customer can grab it, twist it slightly, and lift it off before using the product.

I have a feeling I’ve seen something similar in another industry, but I can’t remember where. It could be from cosmetics, food packaging, paint, medical devices, or something completely unrelated.

I’m not looking to reinvent the wheel—I’m hoping there’s an existing product, component, or mechanism I can learn from.

Has anyone seen anything like this or know what I should be searching for? Even if it’s from a completely different industry, I’d love to see examples.

Text phone number/app

For my small business, I would like to have a second phone number that I can put on my packaging so that people can text me feedback.

I live in a small community, so it’s not like a lot of people will be texting me, but I still don’t want to give out my phone number.

Is there an app or service that I can purchase where basically I would put this phone number on the package, and people will text me…. And it will go to an app (or going to my phone number is fine, I guess). This is for actual back-and-forth conversations. It will not be AI. And it won’t be used for any sales or marketing. This will be just for a short period of time while I’m testing out a product.

Is there an app or service out there? That’s like that?

Hi everyone,

I’m looking for a photographer in the Dallas–Fort Worth area for a shoot for my website. I’m specifically looking for:

- Black & white, editorial-style portraits (clean, minimal, a bit artistic)

- Someone who can also capture polished, professional headshots

- Experience with lighting and composition for a more elevated/luxury feel

Ideally, I’d love someone who balances creative direction + professionalism — not just standard headshots, but someone who can guide poses and create a strong visual mood.

Any recs would be greatly appreciated!
