Print Recommendations:
Standard PLA works perfectly for this model and is completely sufficient for everyday use! If you plan to use the rig heavily outdoors in direct, hot midsummer sun or leave it in a hot car, you can optionally opt for PETG – but for normal use, standard PLA is absolutely fine.
To ensure the parts are strong enough when you melt or press in the brass threaded inserts, I recommend using at least 3 to 4 walls/perimeters and an infill of around 25% – 40%.
