Prusa i3 Mk2 filament guide

thingiverse

This is a filament guide upgrade for the Prusa i3 Mk2 printer. A full roll of filament often falls off the sides when the print head reaches its maximum height and is positioned near one side or the other. The original clip-on guide attaches to the frame and can be easily detached. However, I added an upgraded filament guide with a slot in it to address issues with stiff filaments that can snap during tall prints. The single-hole guide does not flex enough when the print head approaches its maximum height, causing excessive bending of the filament. In contrast, the slot guide allows for more flexibility, enabling the filament to angle and follow the print head without excessive strain.
