Hi Mira,
This is Bogdan from Romania.
I'm a mechanical engineer - specialized in the industrial robotic field, 3D designer and modeler (from time to time and some projects I could make the functional prototype too).
I'm doing product design, industrial design, reverse engineering, ideation, etc.
I have over 15 years experience working on various systems/devices across multiple industries, from concept to launch.
1 - i have such an activity table for my daughter, but is a single piece table top and the legs
2 - as you need/want to have extruded profiles, will also need snap-fit corners which also to accommodate the legs
we could work on this project, but i like to think you are aware the price would be different than my bid...
For any more questions we could chat here.
Regards
Bogdan
