Stackebale furniture/shelf legs
Made these legs for a custom shoe rack. But the legs could be used for all sorts of furniture, like an shelf.
My version only uses the bottom and top leg, but I also made an leg for a middle section.
The dimensions for the plank used in my project are 800x235x18mm LxWxH
And for fasting the legs I used Ø4mm x 25mm screws.
The fusion 360 files are attached for modification, so the legs can be altered to your project
