Designed in OpenSCAD, fully paramaterized. Converted to STL, resized in Inkscape, and then forged.
Prototyped the joint separately, then made two full size cardboard prototypes, and then a production model. The wood version is strong enough for me to stand on.
Looks really great with that planter shape too! 
Great design! These or a modified version would be good for holding hot casserole dishes in a buffet line. You need to have a fancy dinner party now!
Very nice!
(I know this is a super old thread-- but thought I’d try…) I’m curious about the strength of the cardboard prototypes-- thinking about all of the cardboard furniture out there, I’d guess these might be decently strong on their own, as long they don’t get wet? @pdbogen any thoughts?
They’re pretty strong. They can hold plants without much trouble. Long term, I’d worry about wear and tear. And, yeah, water damage.
I really love these!!! You have inspired me to try my hand at making my own design!
awesome! post pics as you get it worked out.
