Use your 3D printer to create stamps, without wasting time and plastic printing excess handles. This reusable handle mounts to your stamp designs using a single M3 socket-cap bolt (8mm-16mm).

One example stamp included. Apply directly to forehead for best results. For external use only.

(Triangle design shown in the example photo is not included, but could be easily recreated by combining other designs I've posted...)

Making your own stamps: Use the included stamp-blank.stl model as the basis for your custom stamps. It includes a recessed receptacle for an M3 socket-cap bolt. If you stay within the lines and your stamp details are roughly 4mm thick or less, stamp-cover.stl will fit over your stamp and keep it from inking things accidentally.
