I decided that I didn't want my utility knife blades just lying around so i got online and found the original model, but it did not have a way to hang them from a screw so i  added a slot for hanging it and printed it.  Well, it was too small for my STANLEY blades so i had to resize it and well It works great holds the blades securely and the convenience of hanging them from a screw out of the way from the work bench, Just What I Needed! You will have to use a blade to get some of the extra support material out of where the blades come out, but it works for me!  And as Always Happy Printing!!  Oh, If You make it and like it post it!  Thank you for the original design!    destro4444
