This compass is quick to print and is handy around my woodshop.  I got the idea from John Heisz and his compact compass.  I have a 3D printer so thought that it would be great practice to continue honing my 3D modeling skills and use the printer for useful tools.  

The model has a pre-threaded post that accepts an M5 nut and the hole is designed for a mechanical pencil.  I have created a recess to accept an 18GA brad nail with a little super glue to hold it in place.

I printed it at 100% infill to give strength to the post
