This is a set of some commonly used connectors with the 15-series 8020 bar. Components:
4301, 4-hole inside corner bracket (this one is a bit bendy, consider the gusseted version)
4302, 2-hole inside corner bracket
4307, 2-hole flat plate
4332, 2-hole gusseted inside corner bracket
4336, 4-hole gusseted inside corner bracket (I added a diagonal member since this is plastic. Really sturdy in PETG!)
4442, 3-way squared connector (For connecting 3 bars together at right angles. Note this requires tapping the ends of the bars with 5/16-18 threads)
And also 1- and 2-hole T-nuts with hole sizes appropriate for 1/4-20 and 5/16-18 taps. Those you should print at 100% infill.
I've printed all of these without supports, in the orientation given in the file. 20% infill works just fine.
