Swappable Stamp (parametric)

Summary:

A stamp with swappable inserts that can easily be edited. The inserts are locked in place by a screwable cover.

Model Description:

The fusion file is provided would you want to adjust the tolerances, see how it's done or simply edit the model easily. I also re-created the insert model in openscad to easily customize it with a SVG (easy to do, look in the zip file).

If you don't use CAD yet, check out StampForge, it is an easy online tool made by a fellow printables creator to apply an SVG to a 3d model.
You can upload the blank insert and your SVG there to make your own insert come to live.
Note that for this model you will need a Z offset of -23 (=-diameter/2) and a scale of about 6. The Y offset can be handled automatically or you can use 4,3.

Printing information:

• Split the model to its parts before to print each part separately
  • Print all the pieces in the same orientation as they came except the insert that needs to be printed on its flat round base.
  • All pieces can be printed in a regular material like PLA except the insert that should be a flexible one like TPU.
• No supports are needed
• Ironing (with the 3d printer) the highest surface will improve the finish of the stamp and will therefore improve the stamped results, alternatively you can also sand the model down with a high grid sandpaper (220p works well) afterwards.
• The additional inserts are already correctly oriented

In addition to the model, I provided a blank insert, you can simply add your wished symbol onto it with a height (by default) of 2mm. This can, naturally, also be done via the fusion and openscad files directly of course ro even with the StampForge online tool.

Initially I simply cut open an old inkcartridge I had laying around for the make but it gave quite messy results (see blue make) as usually too much ink was used. Spreading the ink on the insert with something worked better but wasn't practical so I simply bought a 2euro inkpad. The results are much sharper this way (see black make).

• I have made several additional insert packs available for this model.
• You will also find there a storage tube model to store this stamp and all these insert packs.
