Here is a CAD drawing of the device we're using to apply a rotational skin stretch to a user's arm/hand. The device is intended for preliminary testing.

Actual device photos are seen below.

Some of the design issues that should be improved upon are as follows:

• Not enough vertical travel, to allow for larger forearms
• The pulley drive system works well and is smooth, but is difficult/annoying to reattach when the string breaks
• Because the entire system is primarily composed of acrylic, it isn't very accessible or open to changes (i.e. small modifications to the device cannot be made easily)

Here's a list of most of the parts that were purchased to build the prototype
