Spool Roller

The inner holes can be used to mount the rollers perpendicular to the x-axis and the outer holes can be used to mount them parallel to the x-axis. The bearings I used where 20x7x8mm. The 4 bolts to mount the rollers were ANSI #4-40 I cut down. Unfortunately I do not remember the specs on the u-bolts.
