Corner connector for 20 mm profile

Corner connector for 20 mm profile on the print bed
The print preview of the built part. One square is 10 mm.

I have two lengths of 20 mm square aluminium profile with slots down each face, and I need to join them at a right angle so they stay square under load. It should bolt into the slots on both pieces.

Material
PETG
What the tool did
Two arms at a right angle, each seating against a profile face and bolting into its slot, braced across the corner by webs.
