- CubeSpawn proposes a 500 mm modular “cube” form-factor for open-source CNC/3-D-printing/pick-and-place cells, designed so each cube can manufacture the parts for the next larger or more accurate cube, creating a recursive, self-replicating factory chain.  
- The community debated whether to chase mass-production accuracy or embrace ultra-portable, backpack-scale tools; geodesic stiffening, hexapod kinematics, software error-correction, and salvaged CD/DVD-drive actuators were suggested as ways to compensate for lighter frames.  
- A 1 µm-resolution open-source linear-motor design (coils wound on a mill, staggered between plates) was shared along with a white-paper and National Instruments tutorial, illustrating how high-precision motion can be built in a garage.  
- SKDB (“apt-get for hardware”) was introduced: a Python package system that stores CAD in STEP format, YAML metadata, dependency graphs, and provides “make” vs “buy” buttons for every part, with plans to let users upload their current inventory so SKDB can compute the shortest build path.  
- Participants sketched a 3–5-year road-map for garage-scale IC production: maskless lithography using 1970s-class MEMS plus emerging lights-out chip fabs could close the loop on fully self-replicating hardware.  
- Practical bottlenecks identified include surface grinding, precision linear bearings, and thermal error (“on a mill, everything is a thermometer”), while STL is explicitly rejected for precision work in favor of STEP.
