Original Prusa XL comes with two versions of the spool holder. Each version has slightly different parts and different procedures.

⬢Spool-holder-slider (2x)

⬢Spool-holder-base (2x)

⬢Spool-holder-mount (2x)

⬢M5x85 screw (2x)

⬢M5nEs nut (2x)

⬢Carefully turn the printer so that the side with the Wi-Fi antenna and side filament sensor faces you.

⬢Insert the M5nEs nut into the front support extrusion (with the orange plastic cover). Insert the side with the spring (metal plate) first, then push the nut inside.

⬢The M5nEs nut is free to move, you can adjust the position as you want. But remember, the nut must be slightly pushed in to smoothly move. Anyway, we recommend approximately the same position as you can see in the picture.

⬢Insert the second M5nEs nut in the extrusion approximately to the same position as shown.

⬢Attach the spool holder assembly to the M5nEs nut in the extrusion. Note that there is a protrusion on the spool-holder-mount, which must fit into the groove in the extrusion.

⬢Tighten the spool holder assembly.

Keep in mind that if you mount the Spool holder too high or too low, it may not fit the filament spool on it. There has to be enough space around it.
