Connector for aluminium frames

thingiverse

I've built a terrarium with aluminium frames and during a move, some of the connectors of these frames broke, so I needed new ones. On the first picture, you'll see on the left the self printed part and on the right the existing part. I've chose 80% Infill for stability. Tried to make them with Fusion360 and parameters to be able to customize them to many needs.
