Spool roller 1

In the spirit of the spool holders based on 4 bearings.

It measure 112 x 55 x 8 mm

This one is made to fit 240mm diam. spool, 55mm from inside to inside (minimum, you can use longer bolt for larger spools).

That's the stratasys old Dimension spool found in their cartridges, the case is great but you can't see how many filament you have, thus I wanted to take it out.

[15/03/2012] added one for 50mm (smaller) spool
