Hi everyone!

Meet KIDDO (Kinematic and Innovative Device for Dynamic Operation), an articulated, modular and interactive action figure that plays custom voice lines and LED effects, all controlled by a remote. I made it as a personal gift for my nephew, and the baby it carries has his 3D scanned face.

Here’s the workflow:

• Blender for the exploration and character design
• SolidWorks to remodel every part with proper CAD features and design all the joints, snap-fits and internal housings for the electronics (no add-ons)
• KiCad for all the electronics and PCB design

Then everything was 3D printed.

I gave a 20 minute talk about the whole process at the Blender Conference 2026, you can watch it there: https://youtu.be/7NndTBpol5c

The original concept was inspired by the work of Molding Mule (@sohei_hey on Instagram)

It was all fine last night and I came this morning to…. That?

X2D PETG default profile

I designed a semi-automatic bag sealer that uses a clever twist-to-tighten mechanism. By simply rotating two concentric rings, an internal cord tightens around the bag neck to create a secure seal. Perfect for keeping food fresh or organizing components.

The model is designed to be printed in place and ready to use.

I’ve been working on a robotic arm for the back of my SpotMicro over the past few months that was inspired by Boston Dynamics Spot Arm.

The arm weighs around 1.1 lbs and uses MG996R servos. I designed and 3D printed the entire arm myself, making this my first robotic arm built from scratch!

I’m still working on reducing the wobble, and I haven’t tested its payload capacity yet. The video shows it moving at full speed, and slowing it down through the controller helps reduce the wobble somewhat. I also haven’t mounted it to anything yet and would rather not screw it down into a table

For the electronics, I’m using a Raspberry Pi 3B+ and a PCA9685 servo driver. (I also am still working on a GitHub for it)

I’d love to hear your suggestions for improving the stability, reducing wobble, or making the design better. What would you change?

(The arm is printed in petg which allows it to be lightweight and pretty strong I have not seen any bending yet)

Thanks for any feedback!

Any tips on how i can hide these these seam lines , ive sanded prime and bando atleast 4 to 5 times , and recommendations? I will be using rub and buff , anyway I can hide them ? Maybe a black wash ?

Designed this little two way locking mechanism today for an upcoming project. I know there are many proven ways to do this but for me it's always fun to think of solutions and design them by myself i. I'm quite satisfied with how this works, even though it's probably complete overkill for the project.

First time seeing a consumer SLM printer! Company is called SnowX. Honestly pretty blow by it. The build side is tiny though with a maximum build volume of 80x80x100mm.

They say their target audience is mostly jewelry makers, which I can definitely see the appeal. But at a 50k+ yuan (7.5k usd) for the base plus if I remember correctly 500 yuan (75 usd) for 2.5kg of powder, it is definitely not something you would buy just to play with (unless you just got that bag).

They will go live on kickstarter mid next year, what do yall think about it? Would you buy it? What would you need it for? (I am not endorsing or affiliated with them)

My mum got some colour changing fillament because she wanted some stuff printed and it's actually quite cool. A very good way to introduce more colours to a print.

Any Subnautica fans out there?

Had a blast working on these. Subnautica is one of my favorite game franchises of all time, the feeling of bringing props to life from our favorite forms of media never gets old!

The print files can be found at 3d-mon.com.

These were resin 3D printed entirely in Sunlu ABS- Like resin, on the Phrozen Sonic Mega 8KS & ELEGOO Saturn 4 Ultra.

Painted using custom mixed Createx Opaque colors. Via an airbrush & .8mm HVLP gun.

To anyone interested, I just released a YouTube video which documents the entire build process start to finish!

I just finished printing a hueforge this morning. I have printed some in the past, but this one turned out super well and I felt like it was worth posting.

I use Petg to make this, the colors were: black, white, light grey, and blue. Printed on BAMBU lab x1c.

I found this picture randomly online and decided to make a hueforge of it because I was looking for good images to use to make one for my wall.

My first 3D printing project!!!

The links slide in telescopic rails printed with 0.15 mm clearance per side. The sliding faces are printed in the smoothest orientation, because a tilted face gets a staircase texture and jams. Mixed PETG and PLA. All STL, STEP and Fusion 360 files are free: github.com/molanocortes/takto-one

It’s my master’s thesis project and I built it alone, so if you like it, a star on the repo helps other people find it. Happy to answer print questions.

I have been using FDM, SLS and SLA printing as an engineer/creator for a while, and have thoughts I'd like to share and ask what you guys think:

- FDM, kinda always been a hobby machine thing, you couldn't really ever get a super pro one that outperform the rest, and since the "bambulab" style printers, they're very good and reliable enough to objectively be very decent machines

- SLS machines are just out of virtually any individual's budget at best, and prolly will remain a "manufacturing hub" thing for a while, though I'd love to be wrong and have one in my shop ahah

- SLA has been complicated. My experience has been for any non industrial machines, they'll print very intricate objects, but with a fairly bad relative accuracy due to warping, so much so the few machines I had I just gave up on using those parts for engineering purposes entirely, but somehow Formlabs machines could always nail them. But while not SLS machine range, they're still expensive for most individuals, not just the machine but the resin too.

And now here's the thing that just dropped, they just released a new printer, the Form Studio 1 which seems very similar to their Form 4, and I can't really tell the catch from the demo. The printer is 1/4 the price and the resin has both cheaper offerings and also lets you use 3rd party resins from the get go - which Formlabs have always been dragging their feets on.

And so my Q is: what's the catch? My view on the industry is that they would have had to drop their price way closer to competition sooner or later, I just didn't expect it to happen so sharply. Curious to hear what you think!

Just finished printing this!
In the depth of cold space, facing whatever horror lurks in the dark, your communication device will remain safe within the skeletal grip of this alien throne.
Inspired by the dark, biomechanical art of H.R. Giger and classic sci-fi lore, this phone stand is crafted from intricate weaves of bone, vertebrae, and organic conduits.
It serves not only as a fully functional desk accessory but also as a striking display piece for sci-fi fans and collectors.

Printed it using a 0.4mm nozzle on 0.20mm layer, on Biqu Orange Frostbite plate with Bambulab Carbon Black matte PLA on X2D.

This one took around a week of printing all the parts. Paint job took around 6 days. Really proud of the way it all came out. The Wolverine model is not my design, but the custom sentinel base is. Found the Wolverine model on makerworld that was clearly set up to have a base, but no base available in the file. Had to improvise a bit.

There are so many models for holders and brackets that I figured finding one would be the easy part. Then you get into the dimensions.

Something can be almost exactly right, except the opening needs to be a little wider. Scaling it makes the rest wrong.

I’m starting to see why people end up learning CAD for a “quick little print.” I don’t really want to become good at modeling. I’d just like to be able to move one wall without ruining the thing.

I have been working on this Red Hood cowl for a few days now and am so genuinely thrilled with where it’s at so far! Still missing a few pieces and some more paint, but couldn’t help posting the progress!

-3D printed in ABS

-post processed using bondo spot putty and filler primer

-sanding blocks are a must for smooth surfaces it’s crazy how helpful they are

-paint is Krylon Gold, and metal cast anodized red, currently no clearcoat top coat

-side vents are finished with a mirror chrome paint pen that gives a great final color (also allows holes in side vents to stay black adding depth)

In need of great magnets and more than up for recommendations for high quality magnet sources…

Everything you see was made by me. I drew the original concept, sculpted it in Zbrush, 3d printed, then sanded, finished and painted them. Had a blast. Hope you all enjoy them!

Say I had a cube (10x10x10cm) for 1 cm away from a wall I want my infill density to be 15% as i go inward the density can decrease to as little as 5%. Is there a way to achieve this?

Had so much fun with the NFL Halloween coasters that I figured I’d give baseball a shot.

30 teams, 30 different spooky designs, only printed a few at the moment, but printing the rest now. Had a blast coming up with these, and I’m excited to share them!

Which one’s your favorite? Happy Halloween! 🎃⚾

I always carry around a stack of sticky notes at work, but when I had them loose in my pocket they would always end up getting damaged... Not anymore!

The lid is also magnetic, which I didn't see any other similar models have. Really happy with how it turned out! The design prints in place.

Designed by me in blender.
