[New Release] Life-Line v2025.10
Published on October 15, 2025 by Michael Altfield

Friends,

We're happy to announce the release of the Eco-Libre Life-Line version 2025.10.


This release concludes the manual merge of the contributions from volunteer Jack Nugent. It includes CAD designs for the self-cleaning, raw surface water intake and sphinx documentation.

Introduction


Part of the difficulty in completing this merge was the fact that the Eco-Libre Life-Line’s intake system includes expanded metal as a support structure and a fine mesh for preventing debris from entering the raw water intake drum.

Original Expanded Metal (104 MB)


Hatch Expanded Metal (0.1 MB)


We were able to reduce the MemSize of our Life-Line’s Expanded Metal Mesh from 104 MB to 0.1 MB by simply replacing the Expanded Metal Mesh with a transparent solid and a Hatch

Modeling these materials in FreeCAD caused the MemSize to bloat, crashing FreeCAD. In the past month, Eco-Libre founder Michael Altfield published two articles that described the process to isolate these troublesome objects and how to optimize them with a Draft Hatch. These optimizations (as well as simplifying objects like threaded bolts pipes, valves, and steel angle reduced the total MemSize from 114.8 MB to 1.02 MB.

This article is part of a 3-part series:
