Pulley demo using filament as bearing

thingiverse

Looking through thingiverse I see many of you are using nuts and bolts and other things in your designs. I think you can replace much of the external hardware your using, with the filament itself. I used this demo piece to show that it can be used as a decent bearing, and that you can weld it with an extruder. Instructions Print out all the parts. I'm using a printerbot and found that 4mm holes in my model turn into 3mm holes in reality, so you may have to adjust for that. Assemble according to the youtube video here:http://youtu.be/E5XLjEbcVVQ Check out more information about how any I made it on : www.trenchPhysics.com
