Spool roller for Bambu external spool holder

This spool roller snaps over the original metal external spool holder for Bambu X1/P1 series printers. The only hardware required is 2- 608 bearings. Print standing up with normal support. Note: After using the original for a while, I found that the spool would get pulled over the roller and up against the back of the printer. I added wings to the sides to prevent the roll from being able to be pulled off the roller. All files are the most recent revision.
