3:1 Geared Bowden Extruder

thingiverse

This is a list of parts and materials needed to build a 3D printer extruder, along with instructions on how to assemble it. Here's a breakdown of the components and their purposes: 1. Mk7 Extruder Gear: This is a critical component that helps drive the filament through the hotend. It's made of metal and has a nickel-plated finish for durability. 2. PC4-M6 Pneumatic Couplings: These are used to connect the pneumatic system to the extruder. They provide a secure and reliable connection between the two components. 3. 608 Bearing: This is a type of ball bearing that helps reduce friction in the system. It's commonly used in 3D printer applications due to its durability and low maintenance requirements. 4. 625 Bearings: These are also ball bearings, but they have a larger diameter than the 608 bearings. They're used in this application to provide additional support and stability to the extruder. The instructions provided link to a YouTube video that shows how to assemble the extruder using these components. The video likely provides step-by-step instructions on how to connect the pneumatic system, attach the bearings, and install the Mk7 gear.
