Making a Handle: 

The first step of creating the handle that I took was using calipers to measure the acrylic circles that I have attached to my hand wound mechanism. Once I had found the needed base dimensions I went to work on Fusion. The base that would be attaching to the mechanism is quite small so the handles dimensions of the top versus the bottom are very different. After sketching and then revolving on Fusion the following two images are what I came up with, and this is what I sent to the 3d printers

 

After sending the above images to print, the handle came out great and fit perfectly onto the surface.

 

What I have found so far with the handle is that it has actually made the mechanism less smooth and the mechanism I created is quite small and the handle being as tall as it is had added some instability and stickiness to the mechanism.  Finally for a bit of fun, I added an Asa Quaker to the top of the handle as it does not change anything about how the handle is held and how it operates, but it adds a bit of Lehigh flair to my mechanism!
