Bộ nối chồng chân ghế đẩu (Stool leg-stacking device)

We had an expo for our makerspace and needed a tall display stand to demonstrate phone-based scanning apps. Instead of building something, we had the clever idea of stacking two of our stools leg-to-leg, but it needed real stability. Hence, this thing. It not only creates a nice tall display, but it's also a bit surreal and a conversation starter in itself.

To print, you can custom size it by tweaking X+Y percentages to fit the diameter of your stool leg, and adjust the Z height to make the right fit vertically.
