Reinforced 20x20 Corner Bracket

Just saw another bracket for 20x20 profile, and did a new one! It should be suitable for also 20x40 as the inner gap is the same.

Pls let me know if you need modifications on the model & I'll be happy.
Its created with onshape, I can create these kind of models, if you request!
