Concept
- Build upon standard E3D specifications
- Add Scalable Heater Block made of multiples of existing blocks for low cost
- Add a rubber-optimized 3mm extruder. Make extruder flexible to larger filament size
- Add larger filaments, such as 4-5 mm Shilament from the open source Filament Maker.
Experimental
- Adding heater blocks as in Scalable Heater Block requires only that we figure out how to face a hollow brass rod to connect a second heater block if using 2 hollow rods
- If using one rod, it's possible to align both heater blocks as needed by usng the heat break with adjustable endstop (nut on break, or epoxied. This is feasible only in a redesigned extruder.
- To use a stock extruder, we can use a random angle, but cooling fans would have to be redesigned for a random angle. Tbis is the easiest route because we have control over cooling fan design. This route would require no.other change than adding safety stops on X and Y axes to prevent breakage of heater block in fault conditions.
