The Bambu Lab spool holder looks good, but it ain't rolln'. Here a mod that Keeps Rollin' Rollin' Rollin' Rollin'.

Use the 3mf file for print orientation. Please use your own print profiles. No support needed. The bracket is in 2 parts. they are the front and back. Parts are snap in place onto the spool holder. The roller_608 need a brim to print. Brim is options for the front and back bracket, good to have.

BOM:

2 pcs 608 bearings.
