We live in an age of miracles. 3D printing and computational geometry make previously unimaginable geometries possible. From: Kazuki Abe, Riichiro Tadakuma & Kenjiro Tadakuma's 2021 paper – ABENICS: Active Ball Joint Mechanism With Three-DoF Based on Spherical Gear Meshings

A new version of Open Cascade Technology 8.0 has been released. This geometric kernel forms the backbone of several projects such as #FreeCAD, #IfcOpenShell, or #KiCAD. The release announcement is here: occt3d.com/occt3d-open-so… #OpenCascade #OCCT3D #OCCT #OpenSource

Se venció la patente del cierre en "Y", una técnica que permite combinar 3 formas flexibles en un cuerpo rígido. Tiene decenas de aplicaciones desde la robótica hasta textiles y estructuras livianas. Y todo gracias a la impresión 3d.

Genuinely the future of 3d printing

@shinjinof 色々ギアがありますよ、ここに: makerrepo.com/r/fangpenlin/p…

3Dプリンターでスクリーンプリントの製版ができます！ 多分これやってる人いないんじゃ？ （居たら教えて…） #JRRF2026 のブースで展示販売予定です モデル makerworld.com/ja/models/2497…

Turning a cube into an octahedron isn’t magic, it’s discovery. Connect the centers of a cube’s faces and its hidden dual emerges: the octahedron. Same symmetry, flipped structure (6↔8). Geometry revealing what was always there.

WORBY (Wall Organizer with Red, Blue, and Yellow) is a modular system that is designed to be a balance between functional organization and neoplasticism-inspired art. Check out the full project video on my YouTube channel. youtu.be/W9K-JoGDvxo (sponsored)

Woot! 🎉 TinyRack.io 1.2.2 just released! I also added an assembly artifact to show how everything put together 😄👍

Someone just open-sourced a full 3d building editor that runs 100% in your browser. no autocad. no revit. no $5,000 annual licenses. open-source.

BTS of an average day of a mechanical CAD designer

@fangpenlin @MakerRepo Git for hardware. Finally. Tired of renaming files 'final_v3_actual.FCStd'.

So far, the versioned model is definitely one of my favorite features of @MakerRepo. Adding the build number as version mark on the obj is so helpful for prototyping. I can tune params without worrying about confusing between attempts.

Generate 3D-printable cubes/cuboids with ArUco or AprilTag fiducial markers on all 6 faces, then detect their 6-DOF pose from a camera. Aprilcube is a two-part pipeline: Generator -> Creates a multi-color 3MF file with markers on every face, ready for dual-color 3D printing (Bambu Studio / AMS) Detector -> Detects the cube in a camera image and estimates its full 6-DOF pose (rotation + translation) The cube geometry is fully parameterized: grid layout, tag dictionary, tag size, margins, borders. Both modules share the same config, so the detector knows the exact 3D position of every tag corner.

After building 25+ XLeRobots for hackathons, we redesigned almost every structural part except the arms and head. And we’re open sourcing the hardware upgrade behind our XLeRobot build. It’s the actual internal print file we use for customer builds and hackathons. We made it: Easier to print - complete .3mf with tested on Bambu P1S/P2S/H2S/H2D. Easier to build - square side-loaded nut traps that don't fall out during disassembly, snap-on driver board covers (no tools), dedicated USB hub mounts for clean cable routing, quick-release power bank mount, etc. More stable base - bearing-supported omni wheel modules so the axle is loaded from both sides, replacing the stock LeKiwi chassis that wobbles under full XLeRobot weight. Thanks to: @IsaacSin12 @ThomasSchicksal @xu280589 @QILIU9203 @VectorWang2 @LeRobotHF GitHub repo in reply. Technical specs in thread. Here is what we updated:
