The three "V" grooves in each roller adjust to fit spools perfectly and prevent shifting. Depending on the length of threaded rods chosen, SCOPIC can be used with one spool, or multiple spools. Parts Needed: (8) 608XX 8x22x7 Bearings (Skateboard Bearings) (2) 5/16-18 Threaded Rods (cut to any length - 8" Shown) (4) 5/16-18 Nuts Assembly Video: https://youtu.be/w2kbuE8KYGI Print Settings Rafts: No Supports: No Resolution: .2 Infill: 100% Notes: I did my best to make sure all parts could be printed WITHOUT support. Here is my suggested orientations: Sides - Base Down Rollers - Bearing Opening Up Caps - Voids Down (Rounded top Up) Couplers - Round on Table Because of the angles, I would suggest slowing down your print speed and setting a layer height of no more than .20
