Thread wires of load cell through base of spool holder and insert load cell into base. Wires must be on side of base with hole. Insert M10 nut into side of base where wires for load cell are coming out. Using bolt from old spool holder, tighten down base such that directional arrow on outer edge of load cell is pointing straight down. Base shouldn't be able to turn afterwards. If having problems tightening at right angle, try rotating M10 nut in base. Insert M8 nut into slot on side of spool_holder-inner_bearing.stl. Slide inner bearing piece over outside of load cell and secure with another M5 screw. Press bearings into spool_holder-spacer.stl pieces. Press bearing onto spool_holder-inner_bearing.stl piece. Press bearing onto spool_holder-outer_bearing.stl piece. Thread nut onto threaded rod and thread it into first nut in spool base. Tighten second nut to prevent rod from spinning. Slide PVC section over spacers and thread rod into outer piece. Lock outer piece with final nut.
