Step 1 Introduction

Introduction
Introduction
Introduction
⬢The Filament guide is an optional accessory for your Original Prusa MK4 printer. When printing tall objects with a full filament spool, this accessory prevents filament tangling if it falls off the spool to the side.
⬢Where to get the Filament guide?
⬢Factory-assembled printers include the guide (marked E1) and fasteners in the package.
⬢A G-code pre-sliced for PLA (marked R1) can be found on the bundled USB flash drive.
⬢An editable 3MF file can be found on Printables or in the drivers' package.
Note that marking on the printed parts is either Ex for factory printed, on Rx for self-printed. The geometry is the same.

Step 3 Spool holder assembly

⬢Place all three parts in front of you. Note both "arms" are identical. Make sure the C shaped opening, which will snap on the printer's frame is facing you.
⬢Take the "arm" on the right side, insert it gently into the main part and rotate it clockwise. It should take about half the turn to lock the part in place.
⬢Take the other "arm" on the left side, insert it gently into the main part and rotate it anti-clockwise until it locks in place.

It should click in inbetween the top two ribs, pointing upwards, as seen in the photo.

⬢Fix the guide in place using M3x18 screw.

⬢To prevent filament tangling, when a given spool is not in use, hook up the filament end into the small opening on the spool guide.
⬢This comes in handy if you have two spools on the holder.
