Just for the fun I calculated, by Finite Element Method, the maximum weight the hanger could take if printed with 100% infill and using Prusament PETG. I have used the Prusa Technical Data sheet which indicates a Tensile Yield Strength [MPa] = 46 MPa
Force [Newton] | Max Stress Peak [MPa] | Max Displacement [mm] |
| 50 | 15 | 7.6 |
| 75 | 23 | 11.5 |
| 100 | 31 | 15.4 |
| 125 | 38 | 19.2 |
| 150 | 46 | 23 |
| 175 | 53 | 26.9 |
| 200 | 61 | 30.7 |
In theory the hanger could take up to 15 Kilograms before permanent deformation occurs. However the Prusa data was extracted from a tensile test with the force perfectly aligned with the printing lines, such as this:
Whereas on the hanger the printed lines are bent, because the snake geometry. I would say that by applying a 30% reduction margin, because the geometrical differences, the snake could take easily up to 10 Kg. I will do the real life load test with water 1L bottles when I find the time and post here!
