The Answer.

Also, just having fun trying out a some 3D CAD and printing ideas. More versions on the way.

This one : 42 Stamp

This print has two parts - a handle and a replaceable "stamp head." The idea was to create a generic stamp design in which different stamps could all work with the same handle design.

In addition to being a "42" print, this print was a test for making a "rubber stamp." I wanted to see if printing the actual stamp part in FLEX would work better than just a PLA print. To do this, I edited GCode so that I could print partly in PLA and partly in FLEX. I also printed a PLA only stamp for comparison.

As it turned out, the FLEX stamp and PLA stamp worked about equally well; if anything, the PLA stamp worked a bit better. Once thing I did find that improved both stamps was to rub the stamp over a piece of sandpaper to both level and "rough" the surface - this made it hold the ink better.

Print instructions

Use the provided GCode files to print either all PLA, or a PLA-FLEX combination. The handle is PLA only.

General settings for both handle and stamp:

• 15% rectlinear infill
• perimeters =2
