MakerGear Simplified Extruder Block with Quick Release
thingiverse
To ease frequent filament jam clearance or changes, I devised a quick-release mechanism similar to MakerGear Prusa Mendel's extruder design but with a hinged bearing block secured by two bolts. This drop-in replacement requires only additional screws for the hinge and top retainer. In the U.S., a #6 screw of 1.5" length suits the hinge, while the top screws can be #6 sized at least 2.25" or 2.5". The design offers two versions - one with a 4mm filament hole for 3mm filament and another with a 2.5mm hole for 1.75mm. Customizations, like screw hole sizes, are available upon request. To use it, print, assemble, and install the mechanism, ensuring support for extruder block's overhanging back portion during printing.
