Creating a Spork (a mixture between a fork and a spoon) is super simple.
Only four main parts are needed: The handle (an elongated flat cube), the circular body of the spork (a flattened cylinder), the hole which makes the circular body dip down (a flipped half-sphere), and the pyramids which are the fork tongs.
I made the handle around 7 inches long, and 1/4 inch wide. The cylinder that will later be hollowed out is a 1 1/2 inch diameter cylinder, and the half-sphere hole that hollows it out into a spoon is 3/4 inches wide. The tongs on the end for the fork are simply pyramids rotated and scaled to fit on the end of the utensil. They are about 1/4 to 1/2 Inch long (depending on what position they are in) and they are 1/8 inch wide at the base.
It is also pretty easy to position the parts in the correct positions. it really doesn't matter how they are positioned, so long as it will function properly in that position. Lengths and scales of individual parts can be altered as necessary.
Sporks are nice for trips such as camping, because it is only one utensil that serves two purposes.
