Spool Holder Assembly

• Rotate the Prusa Spool Holder Add-On until the PTFE tubes are facing up

Be advised 

@Spacekoaster made me realize that if you use Prusament, there is a small notch in the spool that prevents it from spinning smoothly.  I didn't realized this because i don't use Prusament as much :-(

I don't think this will affect print quality, but just in case, i designed a ring that fits into the middle of the Prusament's spool in hopes of minimizing the bumping effects.

And if you don't want to print and use rings when you print with Prusament,  you can temporarily unscrew the spool holder and screw it back with the Add-On and PTFE tubes facing down

• Assembly
  • Recommended using PETG for the ring
  • Position the ring as shown in the picture
    • Slide the notch into position leaving the rest of the ring at an angle
  • Flip the spool over and push
  • Repeat for the other side

  • Following @Spacekoaster comment i designed a ring that fits in the middle of the Prusament's spool in hope of minimizing the bumping effects caused by the notches
• 2023-09-04 
  • I closed an end on the wide version so the PTFE tubes can't slide by the other side
  • I added an extra wide version to fit 88mm wide spool as requested by Celta
• 2023-08-01 Added a wider version as requested by 3DesignsCH
