I needed a way to attach various items to my balcony railing. I wanted a solution that is reversible and provides a good grip, as I live in a very windy area. That's why I designed these reusable TPU cable ties. They work well for my use case, and I wanted to share the design.

I have designed two sizes, 117mm and 213mm. Even the 213mm version can be printed well on an A1 mini if the object is aligned diagonally on the printbed.

The following print settings worked for me:

• Filament generic TPU, Nozzle Temp.: 230°C, Bed Temp.:30°C
• 0.20mm Standard Profile
• Wall generator: Arachne
• Wall loops: 3
• Sparse infill density: 100%

The model's print duration is approximately 26 minutes, and it only uses 4.2g of filament.
