Pincher V2 - The Ender 3 Adjustable Spool Holder Add-On

thingiverse

LATEST UPDATE: Pincher Version 2 adds a quarter-turn locking mechanism, allowing for faster spool removal with less filament wasted. The system incorporates an adjustable screw function, enabling you to customize your desired level of friction. In pursuit of upgrading my Ender 3, I decided to design and print a custom spool holder add-on that eliminates the need for additional parts like bearings or bolts. This innovative solution not only accommodates larger width spools but also allows for the use of spools with inside diameters up to 72mm without putting excessive stress on the extruder. Key benefits: * Use larger width spools up to 140mm, or two rolls side by side * Utilize larger spools with an inside diameter of 50-72mm without extra wear on your machine * Requires no tools or additional hardware * Works seamlessly with OEM parts * Provides a firm grip for the filament roll * Easy Slide On/Off Design makes filament changes effortless Regular Use Instructions: 1. Remove the original black spool holder and bolt from your Ender 3. 2. Slide your chosen Filament Spool onto Pincher Spool Holder. 3. Tighten the Pincher Tightening Bolt until it makes contact with the Filament Spool, ensuring a secure fit without restricting free rotation. 4. Attach Pincher Spool Holder to the printer in the desired direction. 5. Thread filament into the extruder and initiate your print. Instructions with Added Support (Version 1 Only): 1. Remove the original black spool holder and bolt from your Ender 3 2. Slide on Pincher Spool Holder, positioning it as desired. 3. Insert the original black spool holder into the middle of Pincher Spool Holder until it reaches the end. 4. Apply pressure from within and screw on the black bolt to secure the original spool holder in place. 5. Add your Filament Spool of choice. 6. Tighten the Pincher Tightening Bolt until it makes contact with the Filament Spool, ensuring a secure fit without restricting free rotation. 7. Thread filament into the extruder and initiate your print.
