fourth attempt at uploading this. i have downloaded and used several other designs and while they did work i wanted to design one that worked better. this design has the bearings set at 45 degrees from center ( 90 degrees in relation top each other ) which creates minimal surface contact and maximum effect. this also keeps the spool centered so there is no drifting while un-winding. print 2 and requires eight 608 bearings.
