Filament Guide for Original Prusa i3, version 2.0

thingiverse

This is version 2 of my simple filament guide for the Original Prusa i3 MK1 or MK2. Like the first version, this guide lets you leave the filament in a box while printing, making filament changes easy. Improvements: It attaches to the back of the frame rather than the front, allowing the printer to use its full build height. It is tall to ensure the filament enters vertically even when the carriage is high. The attachment has a small lip to grip the frame. The guide has a tighter curve to better 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 the filament from the extruder. It also has a shape that prevents the filament from slipping out of the guide accidentally. I printed it in black PETG. I added the holes in the riser to prevent warping while printing. I've been using this filament guide daily for months with no problems. Update: Version 3 is 5mm shorter to fit inside my enclosure.
