He's a way to display and pose your Dummy 13 on your HSW. I remixed the insert, adapter, and joints to make a flexible way show off your figures.
You can print as many connector pieces as you need, I used 6.
ONLY printed and tested with PETG as PLA usually cracks when you snap the pieces together.
===== UPDATE February 2, 2024 =====
Added Desk / Tabletop Base for HSW Display Arm so you can now have it on your desk or tabletop.
Also verified that this seems to work just fine with PLA
