8020 15-series bracket collection
Description
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.
