In addition to the printed parts, you need to get a spring and a M5 countersunk screw. If the razor is going to be in a rotation, I would suggest that they both be stainless steel. The bolt does not have to be as long as the one in the image and the spring has been problematic for me to get. Neither of these are stainless steel but are good enough for me to try the razor out provided that I dry them properly after use.
