PTFE Bushing / Bearing

thingiverse

This is a 3d printed bushing that uses 3mm ptfe tubing as the contact surface. The tubing travels through the 3d printed casing in a spiral pattern to assist in even pressure around the shaft that it is traveling on. There is a small amount of preload between the tube and the linear that you will be using. Diameter of the bushing is 15mm with a length of 13mm, if you would like it longer simply scale it up in your slicer along one axis. Also, besure to double check your slicer settings before printing as the piece is pretty thin in some areas, you want to make sure that the outer perimeter is one consistent extrusion.
