Furring Strips Coupler (adjustable height conversion)

Edit: added another model that uses less material and with tighter tolerance for an even better fit for most standard furring strips (Common: 1 in. x 2 in. x 8 ft.; Actual: 0.656 in. x 1.468 in. x 96 in.).

Added a coupler for 2"x1" furring strips for @CitizenGreyArms USPSA Target Stand.
This allows the user to connect multiple strips in a row for an easy-to-transport adjustable height target stand.

Can be drilled and used with [clevis pins](https://www.amazon.com/014973472795-472795-Clevis-Business-automotives/dp/B0B6ST6HMD/ref=sr_1_7?crid=24BFQG501KK3K&keywords=clevis+pin&qid=1697479940&sprefix=clevis+pin%2Caps%2C78&sr=8-7) to secure the strips in place.
