About this 3D model
here is my attempt at a printable filament spindle. I based the measurements off the MK1 spindle so it should fit the 5lb rolls sold by Makerbot and Ultimachine. Hopefully the amount of expansion that I have with PLA is common so that the models fit together. The Waxman Lazy Susan bearing(Model #: 4650699NN) is available at Lowe's for about $4.50 US
