Hats off to our collaborators from Poland for open-sourcing a manual, dual-block CEB press. It is in the pre-alpha v0.1 release stage.
You can download the existing CAD files here. The files are in Polish, so they still need to be translated for the broader audience.
Meet your developers from the Co-Habitat Platform: Pawel Sroczynski and Remik Karbowiak. These guys are pretty good. They also developed a model open source, prefab, straw-bale house design, and they will be buildng it this year at a budget of $7k. I always thought that straw bale is too exotic in practice because of the huge labor requirements, but these guys are showing otherwise with OpenSTRAW:
Here is the building sequence. Click on the following images to enlarge:
Both the manual CEB press and the straw bale work are a major contribution to open source economic development – and to humanity. See their website for more information. Congratulations to the Co-Habitat team. We’d like to add the manual CEB press to the Factor e Farm product line as soon as the machine is tested in the field, and we may end up building some straw bale here after all.
