After the hinge broke for my Stainless steel, round, trashcan i've created a re enforced one that is still going strong for 2 years.

The hinge is best printed with:

• Walls: 3
• Infill: 15% or 20%

Extra: cut 1.55 of the top hinge part like in the picture if you don't want to print with any support as this will also put the part on a angle that makes it stronger.
