Concrete rebar distancer / spacer

A simple distance to keep the rebars in position I wanted. The concrete thickness was 10cm and I had 2 "nets" or how it is called :). The rod diameter is 6mm and the heights is about 3cm. I used about 20 of it.
Specially designed to let the concrete easily in.

I shared also the Inventor file to let you modify I tried to make it parametric but there are probably some bugs in the model, so you will need to tweak it a bit in the Inventor.

If you are interested in different size, let me know
