Linear Spool Bearing, Filament Guide & Spool End Cap

Here's a little linear bearing that can be used with 3/4 inch dowels (I cut up an old mop handle). You'll need about 80 BB's for it to work, some lubricant would help also. The outside diameter of the bearing is 54mm and should fit filament spools purchased from filaments.ca. A filament guide and end cap are included.

Thanks , hope it works well!
