Keep your window or door locked open at a full 90° angle – no more windows slamming shut in a draft or doors swinging closed on their own.

This stopper wedges between the door/window and frame, holding it securely open. Its angular, open design keeps it lightweight while staying strong enough to resist wind and accidental knocks.

Features:

• Works for both doors and windows
• Holds open at a fixed 90° angle
• Lightweight open-frame design (less material, still sturdy)
• No supports needed

Print settings:

• Layer height: 0.2mm
• Infill: 15–25% (this part takes some mechanical stress, don't go too low)

Dimensions:
105 x 75 x 18.5mm
