About this 3D model

As with all Makerbots this has the dumb old fashioned filament tube that causes 90% of filament jams, so I made this top mounted spool mount that does not require the tube and feeds the filament directly to the extruder but as I hate spending 20 hours printing a silly spool mount for my printer so I made this, it prints in less than 4 hours but requires 6mm & 8mm Round tubes (carbon,Brass or Aluminum) thus reducing the print time by less than 1/6 th . Almost no friction and no ball bearings required. I have also added 2.5mm holes should you require to add M3 mounting screws. !Note: Print twice (Left and Right sides) !Don't forget to CHECK OUT my other designs and FOLLOW my daily KooKoo uploads, Enjoy ;)
