The handles at my local store are very fragile, are were breaking at least two times per year. After I got a 3d printer, I created this model that feels very sturdy, and matches perfectly with my window mesh. Here are some measurements:

• Distance between screw holes:50mm
• Lenght:70mm
• Width:15mm
• Height:18mm
• Thickness:3mm
• Screw diameter:4mm
