Milling driftwood signs

I spent some time last week getting the Chicago Public Library Innovation Lab set up with a special Shapeoko made by Edward Ford. It is fully enclosed with an integrated vacuum system, so it is both clean and quiet. It has a special spindle too, which makes it even quieter than the laser cutter air filter system!

The first job we ran on it after I fixed a couple calibration issues with it was a driftwood sign for a guy who wanted to make a number plate for his parents house for the holidays. Inexpensive but very thoughtful gift!

3D printed stamp pad

My girlfriend won a self inking stamp pad from Instructables for this stamped canvas bag project. They are pretty awesome mechanically: they flip the design over and get inked internally, then the pushing motion flips it back over facing the paper. But I also wanted to be able to make my own stamps.

Using TinkerCAD I extruded an SVG into 3D to about 2mm high, then put a 2mm platform underneath that design and fused those together by grouping them. The platform was about 40mm square, and it fit perfectly into this stamp pad with some double sided tape. 

As you can see, the 3D printed plastic doesn't take the ink particularly well, so it doesn't make the best looking designs. I ended up taking a piece of unmounted linoleum and carving a design into that, and cutting it to 40mm on each side with scissors. Makes a better stamp, but of course it isn't totally automated!
