Interchangeble Stamp
I didn't expected high quality stamps and I must say my expectation was spot on. I like the result knowing it is not that great job.
If rubberstamps were used it would be nicer.

made with 4mm wood (and a rubber band to hold the stamp frame and the changeable the part that you can put in the ink translation needed ;) is also made of wood and is not sanded.

for best result use a material that is better to to make stamps (like rubber)
the construction itself require glue
I am waiting for new parts to make a new version.
things to change:
The rubber band: it does function but it's ... it is just not what is want, it's going to be replaced with magnets
wooden stamps, when sanded it may improve quality but I'll replace it with rubber
Corners of the base plate of the stamp going to be 'inward' (?!). when done the replaceable part can be replaced with less change that you end with ink on your hands
