Simple filament spool holder

thingiverse

Yet another filament spool holder...\nI was searching for a filament spool holder that meets my requirements:\n)fits 2kg or more spools\n)remains compact\n)simple\n)features ball bearings --> friction test: http://gph.is/2lKmGoh\n)and adjustable friction\nGiven the numerous spool holders available on Thingiverse, I was surprised not to find one that perfectly suits my needs. So I designed this. Due to its simplicity, it's a bit wobbly but gets the job done.\nAdditional items you'll need:\n)8mm threaded rod\n)2x 8mm nylock nut; alternatively 1x nylock and 1x normal nut\n)4x 8mm ball bearing\n)a pipe wrench for drilling the rods into the holes (should be tight enough to prevent further nuts from being needed)\nPerhaps the holes in the spool holder are too loose with your printer's tolerances - if that's the case, please let me know and I'll decrease their size.\nedit:\nA warning!\nThis design has a flaw. After using the spool holder for some time now, I have problems with the thread of the rod moving in the notch (after it cuts a guidance in the plastic over time) so the whole rod gets pushed forward and eventually drops. If you still want to use it, cut the main rod in half and reverse the direction of one half so that - if rotated - the notches get attracted to the center point. That should fix it. You just need some kind of collar to keep those two pieces together.\nI hope this is comprehensible in some way. English is not my primary language.\nPrint Settings\nPrinter Brand: \n Wanhao\n \n Printer: \n Wanhao Duplicator i3 V2\n \n Rafts: \n No\n \n Supports: \n No\n \n Resolution: \n 0.2mm\n \n Infill: \n 20%\n \n Notes: \n Printed in black and white PLA. \nYou'll need to pause at height three times to insert the ball bearings and the nylock nut! \nI've inserted a nylock nut in both of the screw handles but I guess it would make more sense to insert a normal nut in one of the handles to make changing spools easier. However, I cannot tell if that keeps the two cones firmly together in the long run.
