Portable Filament Extruder Build -- 2

I want to put a compact filament-making machine on my workbench that turns either raw plastic granules (my first choice) or recycled PET bottles into consistent 1.75 mm or 2.85 mm 3D-printing filament. To get there I need someone who can handle both the electronics and the mechanical side, design every part so it can be printed on a regular FDM printer, and then guide me through a smooth, hands-on assembly.

The whole unit must stay truly portable: easy to carry, easy to take apart, and just as easy to reassemble so future repairs never become a headache. Quick-swap wear parts, sturdy frame components, and clear wiring layouts are all essential because long-term durability matters as much as plug-and-play maintenance.

Deliverables I expect from you
• Complete 3D-print-ready CAD files for every custom component
• A vetted bill of materials with links or part numbers for off-the-shelf electronics, heaters, motors, and sensors
• Step-by-step assembly documentation (photos or concise video clips work)
• Firmware configuration or control software settings that let me dial in temps and extrusion speed for both granule and PET inputs
• One post-build support session to answer questions once I have the parts in hand

If you’re comfortable blending mechanical design, basic electronics (drivers, thermistors, heaters), and practical DfM thinking so the machine stays light, modular, and tough, send me a message and show me a sample of similar hardware you’ve already brought to life.
