IMPORTANT:
Using the switched fillament guide with very high models crashes the extruder!
Please be aware of that!
I am planning to update the model as soon as possible to remove this issue.
After my original and reprinted filament guide broke I was searching for a better filament guide which could endure more force in the case of a filament knot. https://forum.prusa3d.com/forum/english-forum-original-prusa-i3-mk4-hardware-firmware-and-software-help/filament-guide-broken-twice
I found and made the great model here with a short arm that is directly mounted on the frame similar to the filament holder (see https://www.printables.com/model/517659-filament-guide-for-prusa-mk4/comments/1584025).
After installation I found that a modification of the holder orientation would give even more stability, though reality proofed my wrong the knot in the filament will apply a force that pulls my switched version of the frame.
IMPORTANT:
The guide will NOT be damaged though.
So I used my Code-CAD tool ([build123d
]https://build123d.readthedocs.io) to cut the model in half and turn the foot 180 degrees.
There is another model that does a similar thing but only rotating it 90 degrees.
I hope this gives everybody a quick and easy choice of the best use-case.
You can use the model file 789198a-filament-guide-MK4.py to experiment with the angle
The Vogon demolition ships hang in the sky exactly like bricks don't.
The author remixed this model.
Foot is turned 180 degrees to have the best result if force is applied to the upper arm.
I thought this would be to more stable version, though reality proofed my wrong.
A filament knot will pull ov my switched version. Though the guide will NOT be damaged!
