Various base models including stamp heads, screw-on attachment to preexisting seal handles, long handle and knob versions. Import your SVG/model/other design into the face of one of the stamp heads and cut (mirror your design if it has text).
Files Blank, Blank_groove, Stamp_handle, Stamp_knob, and Stamp have indentations for 3mm H x 5mm W magnets so that you don't have to keep reprinting the whole head/handle. Makes for quick swapping of stamp faces if you're a mad stamper. There is also a pointer on the head to keep track of orientation of design.
There is also a rose stamp and svg as an example for what you can do.
It's best to use a resin printer since it keeps the best detail and won't deform from the heat of the wax.
