Strong suppportless arm

All the stl's are in printing orientation! No need to rotate them!

Print settings
0.2mm layer height for every part. NO cooling, otherwise cracks may appear due to high layer stress. In order to prevent overheating, I strongly recommend you print parts in pairs (elbow_1 + elbow_2). Some of them are already paired (wrist, shoulder). No supports required!

Screws, nuts
1. M2.5 screws, 20mm, 7 pieces
2. M2.5 nuts, 7 pieces

I may add a Fusion360 file later on. It includes parameters, which can be adjusted, depending on your screws and nuts sizes. Those are tricky to change and will probably require editing fillets etc.

So what about load capacity? Well, it holds my Samsung Note9 rather well if you position it properly (can be seen in the photos below). I have no doubt about lavalier mics, lenses, and small tools.
