Would you sell printed parts for a licensed DIY electronics project?

Hi everyone — I’m looking for feedback from people who actually run print farms or sell 3D printed parts.

I’m the maker behind Keymera, a tiny 3D-printable keychain camera project. It’s a small DIY camera built around standard off-the-shelf electronics, with a printed shell, microSD storage, one-button capture, and a Wi-Fi photo gallery.

The project was recently funded on MakerWorld, and I’m now working on the commercial/seller side of it. I’m considering a commercial license for small print farms / Etsy sellers so they can legally sell printed Keymera shells or printed parts in their own shops.

Important clarification: this would not be a full electronics kit. Sellers would mainly offer the printed parts/shells. The customer would source the electronics separately using the BOM and build guide.

One of the big reasons I’m thinking in this direction is the regulatory/support side. Shipping full kits with electronics, batteries, or finished assembled cameras seems like a very different business: CE/product compliance, battery shipping rules, EU battery obligations, WEEE/e-waste registration, support, returns, liability, etc. Printed parts seem much cleaner — but I’d love to hear how people here think about that boundary.

For people here who sell printed parts, I’d love your honest take:

Would “printed parts only — electronics not included” create too much customer-support risk?
Would you consider listing something like this if the package included print settings, photos/renders, suggested listing copy, and clear customer disclaimers?
Would the electronics aspect make it more interesting, or would it scare buyers away?
What would you need from the designer/licensor to make this practical for your shop?
Would you ever consider selling a full kit or finished camera, or would that immediately become too messy because of certification, batteries, and liability?

Thanks for any feedback. I’m trying to understand what would make a licensed printable product actually useful for small print farms.

Keymera - 3d printable keychain camera - launching soon on MakerWorld

I’ve been working on this for a while, and I’m finally getting ready to launch it on MakerWorld - either today or tomorrow!

This is Keymera — a tiny working camera you can 3D print, build, wire up, and clip to your keys.

It’s built around:

5 printed parts
4 electronic components
3 MP camera
microSD storage
one-button capture
Wi-Fi photo gallery
no app, no account

Short press: it wakes up, takes a photo, saves it, blinks, and goes back to sleep.

Long press: it opens a small Wi-Fi gallery so you can download the photos from your phone or computer.

The MakerWorld campaign is launching soon here:
https://makerworld.com/crowdfunding/280-keymera-3d-printed-keychain-camera

I’d really love feedback from this community before launch — especially on the build, use case, and whether this feels like something makers would actually want to print and carry.

And if you like the idea, following the project would help a lot.

Tiny 3D-printable keychain camera

A tiny working camera you can print, build, and clip to your keys.

It takes photos, saves them to microSD, and opens a little Wi-Fi gallery on your phone without an app.

The best part is that the shell pieces can be printed in different color combinations, and fuzzy skin gives it a faux leatherette camera texture.

I made a 3D printable keychain camera

After months of work, it is finally done! A small 3d printed keychain camera anyone can build by themselves at home in one day. Shoots 3MP stills. The design is interchangable and with 4 parts it offers virtually infinite color combination possibilities.

I made a tiny 3D-printable keychain camera you can build yourself

I’m the person behind this, and I’m really excited to finally show it properly.

This is Keymera — a tiny working camera you can 3D print, build at your desk, and clip to your keys.

The idea is simple: a real little camera that feels like a maker object again. Not an app. Not a phone accessory. Not a smart device. Just a small thing you print, assemble, carry, and press when you want to keep a tiny moment.

What it does:

takes real 3 MP photos
saves them to microSD
opens a Wi-Fi photo gallery in your phone browser
needs no app, no account, no cloud
sleeps quietly on your keys until you press the button

Short press: wake → shoot → save → blink → sleep again.
Long press: open the Wi-Fi gallery.

The build is intentionally small:

about 1 hour to print
about 1 hour to assemble
5 printed parts
4 electronic components
4 solder joints
no screws
no glue
Arduino IDE firmware

There are 3 exterior designs at launch: Rangefinder, SLR, and Instant. They all share the same inner frame and electronics, so the outside changes the whole personality without changing the build.

And because the visible shell pieces are separate, your slicer basically becomes the paint shop: mix colors, do retro camera combinations, go bright and weird, keep it monochrome, use translucent parts, or turn on fuzzy skin to get a faux leatherette camera texture.

There’s also a 4th TLR-style shell planned as a stretch goal.

I made a tiny one-button camera with an ESP32S3

I’ve been working on a tiny printable camera that I wanted to keep as approachable as possible for hobby builders.

It uses a Seeed XIAO ESP32S3 Sense, a small battery, one button, one LED, and microSD storage. The whole interaction is built around one button:

Press once and it takes a photo.
Hold it and it opens a Wi-Fi gallery.
No app, no account, no screen.

I made a tiny camera you can clip to your keys

I made this tiny working camera because I love small objects that do one thing clearly.

It’s called Keymera. It has a 3D printed body, a tiny camera board, a battery, one button, one LED, and microSD storage. 3 different exterior shell designs inspired by classic cameras. With a 3D printer, you can create whichever combination fits you best!

Press once and it takes a photo.
Hold the button and it opens a little Wi-Fi gallery so you can download the pictures.

It’s not trying to replace a phone camera. That would be impossible and also kind of boring. It’s more like a tiny object you build, carry, forget about, and then use for small accidental memories.

Tiny 3D-printed camera object I designed

I designed this tiny printable camera and wanted it to feel like a real little object, not just an electronics box.

It’s a working camera, but the shell and color combinations are a huge part of the fun. I wanted it to sit somewhere between toy camera, keychain object, and tiny retro gadget.

The body is 3D printed, the camera is real, and the whole thing is small enough to clip to keys.

It has 3 exterior body design shells inspired by classic cameras - SLR, Rangefinder and Instant.

I’m still testing colors and finishes. Bright contrast looks fun, monochrome looks cleaner, and the more retro combinations make it feel like a tiny camera from another timeline. The options are unlimited - I'm also playing around with fuzzy skin as faux leatherette.
