Extruder Filament Guide for the MK8 Bowden Extruder Upgrade Kit on the Ender 3

I needed a high-quality filament guide for my Bowden extruder on my Ender 3. Unfortunately, none of the ones I found met my requirements or fit all the holes correctly (filament, axis, screws). That's why I designed this custom filament guide that can hold a ball bearing or pulley to feed the filament into the extruder without causing any wear and tear. It has a snug and precise fit without requiring disassembly of the z-axis. All that's needed is to unscrew the two screws connecting the carriage to the threaded rod, assemble it, and then put the screws back in place. This custom filament guide is specifically designed to work with the MK8 Bowden Extruder Upgrade Kit from Amazon and may not fit on the factory Bowden extruder. Additionally, the dimensions are optimized for holding a pulley or ball bearing with the following measurements: * 3 mm (inner diameter) * 12 mm (outer diameter) * 4 mm (height) I used the V623ZZ pulley, but any bearing with matching dimensions should fit perfectly. To secure the pulley in place, you'll need an additional M3 x 16 screw and a matching M3 nut. The filament guide has the following dimensions: * 23 mm (height) * 30 mm (width) * 29 mm (length)
