EDIT 02.03.2026: Added an alternative version with grip grooves, which can provide improved grip in certain door and flooring combinations.
The Flex-Hex-Hook is a compact, flexible door and window stopper optimized for TPU printing.
The combination of:
Curved hook geometry
Shock-absorbing TPU
Hex honeycomb lightweight structure
provides a secure hold while preventing hard impacts or scratches on doors, floors, and window frames.
Ideal for:
Room doors
Balcony doors
Windows
Narrow and wide door gaps
Sensitive flooring surfaces
TPU also adds natural anti-slip properties.
The model is scalable to fit specific needs or unusual gap sizes. However, the original dimensions are designed to fit most standard doors and windows without modification.
