45x45 aluminium profile table leg bracket

I designed this part, to fit some of my university's projects, where we made work tables out of 45x45 profiles from Minitec. The floor side is meant to spread the area of contact, creating a little bit of a stable base. These can also be used to adjust the table height in a limited space to ensure the table is level.

Added screw holes, to attach it to a wooden tabletop. The aluminium profile is attached with M8x16 bolts used.
