Filament Guide for Original Prusa i3, version 2.0

thingiverse

This is version two of my straightforward filament guide, designed specifically for the Original Prusa i3 MK1 or MK2. Just like the initial version, this updated guide enables you to leave the filament in a box while printing, making filament changes remarkably easy. Enhancements include: It attaches securely to the back of the frame rather than the front, allowing the printer to utilize its entire build height. It is tall enough to ensure the filament enters vertically even when the carriage reaches maximum height. The attachment features a small lip that grips the frame firmly in place. The guide boasts a tighter curve to more accurately match the shape of the incoming filament. As before, the guide has a channel at the top so you can remove the filament from the guide without removing it from the extruder. It also incorporates a design element that prevents the filament from slipping out of the guide accidentally. I printed it in black PETG and added holes to the riser to prevent warping during printing. I've been utilizing this filament guide daily for months with no issues whatsoever. Update: Version three is five millimeters shorter, allowing it to fit neatly inside my enclosure.
