Flex feet for 40mm T-slot

These adaptable filament feet fit snugly onto this printer: http://www.thingiverse.com/thing:273890 The T-slot extrusion is specifically designed to work seamlessly with M8 bolts. Simply thread the inside of the extrusion, print the feet using flexible filament (or choose a material that suits your needs), and carefully insert a 20mm M8 bolt through the feet up into the extrusion. To achieve optimal results when printing in flexible materials, make sure the M8 bolt runs smoothly through the extrusion before attempting to screw it in place. If not, the bolt head may not provide enough grip to secure the bolt tightly. Instructions: Print the feet using a flexible filament of your choice. I personally used 15% infill and applied three layers on top and bottom, with two perimeters for added stability. To complete this project, you will need an M8 20mm hex-head bolt (also known as a hex outside-head). First, tap and thread the T-slot extrusion to ensure it is clean and free from any obstructions. Finally, screw in the feet by hand until they are snugly tightened.
