Aluminum 2020 Extrusion Corner Brace

I designed this to brace the corner of the lid on an Modix Big 60 printer, but it can be used for any 2020 aluminum extrusion and M5 t-nuts/screws.

For the Modix printer, the standard low-profile head screws used for the rest of the enclosure are a bit long, so also print the 4mm thick spacer to take up the extra length (otherwise the screw will bottom out in the t-track, and not work).
