This Pen Holder can be used to draw circuit boards with an etch resistant pen and is printable on a 3D printer.

This 43" tall, 46" square dining table assembles with no hardware or glue. It is incredibly sturdy.

The table is square because it promotes better community with no one placed at the head of the table and everyone equidistant, allowing for better conversation.

The table takes 2 4"X8" sheets of 18mm plywood. Most cabinet grade plywood from Home Depot is 18mm and inexpensive. The one in my home is made from high grade birch ply.

Someday, I will alter the design to allow for an expanding top to accommodate 8 people.

I've added a photo of it in our home for an idea of how big it is.

An eight-legged big spider robot.

The design goal was to create a legged robot that is large enough to walk regular stairs and strong enough to lift simple loads. It also had to be simple enough to use regular RC-srevos and could be cut with my minimal CNC machine.
