single edge razor blade handle

cults3d

This is an easy to use handle for single edge razor blades. The plans are right hand oriented, but can simply be mirrored for left hand. There are 3 versions of the STL file- (A) is as shown, with the hole to be threaded 3mm. (B) is with a clearance hole to be used with a nut and doesn't need threading. (C) has a recessed nut that can be glued in to eliminate losing the nut. The plan is a very snug fit for the blade to eliminate wiggle, so depending upon your printer the little positioners may need a small amount of filing or sanding to get a proper fit. Shown are three fastener options, and I can provide various plans for the printed one on request. The design allows an unobstructed view of the blade edge.
