I'm working in a low-budget CNC with 2020 Al profile extrusions and 3D-printed parts.
This is the mount for the moto-tool that I have. :D

A straight forward design in regards to capture certain degree of freedom & surface pressure, the T-Plug.

Repeatable Ornament
I'm surprised how well FreeCAD 0.20.28611 is suited for modeling complex curved bodies. All I needed was the Part and Draft workbench and a self-made macro to sweep along two rails. FreeCAD was able to generate an error-free solid from all objects, which could be rendered perfectly with e.g. Blender (see pictures).

Wow, that is really impressive! I must say, that i am not the artistic type, but this is really really impressive. This is even in a high end commercial CAD with special license modules pretty hard. But with FreeCAD, which is not that good freeform surface modeller,

respect!

Thanks for sharing. Would you mind publishing the macro?

Hi Chris,
I have put together a small tutorial consisting of a PDF, the FreeCAD file and my macro DistributeProfilesOnRails. You can find it under https://forum.freecadweb.org/viewtopic. ... 47#p587147. Have fun with it!

because it was so shiny red. It also was a slick simple design. The original called Fireball Tools DIY vice has some thrust bearings,
i did not include these... My model is not the one from Fireball Tool, i did not buy the plans, i don't provide the welds for joining
the sheet metal, my dimensions are not related to hardware you could purchase. The purpose of my model is to have a idea of
the design. You may wont to alter the model for your needs if you choose to make one of these for yourself.

CAD and STEP model are available here: https://grabcad.com/library/diy-vice-1
That looks very cool and a great example on how to use FreeCAD.

Thank you jhaand :).

Here is a sneak a peek of a abandoned project. I had a toy MUTT for 3D print in mind. Maybe as FreeCAD
progresses i will come back for this project... (probably not).

Hello Community,
I am currently working intensively with generative designs. My goal is to use FreeCAD for projects that I would normally use Rhino's Grasshopper or Blender's Geometry Nodes for. To start with, I have been working on a DualMesh implementation. With the attached scripted FreeCAD object "DualMesh", triangle meshes can be decomposed into their dual representation. If you are interested, simply download the module "DualMesh.py", move it to your macro directory and execute the following code from your FreeCAD terminal (don't forget to start by creating a new FreeCAD document):

Code: Select all

import DualMesh
DualMesh.makeExample()
The code creates a mesh ellipsoid and generates the corresponding dual mesh as a clean solid. Scaling of the generated elements and extrusion thickness can be varied parametrically via corresponding properties (see figures). This can be done with all triangular meshes from Mesh WB.
