About this model

Attach a third or forth monitor to your setup that already uses monitors arms with 30x20 mm square tubing I recommend lightweight monitors because it's held up entirely by screw tightness; for this reason, I also recommend materials with lower creep, such as PETG, and largely avoiding PLA. Hardware: M5 heat-set inserts and M5x12 Bolts
