Similar design to injection molded ratchet clamps you can find on the market.
I use it to organize power cords.
Hooks snap firmly in place but can be opened by twisting.
The inner diameter is around 35 mm. Haven't tried resizing in a slicer yet.
Those were my first printing attempts with ABS (gray part). I actually like the overall look and feel of the part compared to PETG much better. However, both materials work.
2024-03-25 Update: I've added a rectangular/trapezoidal version, which makes resizing in Fusion easier. Open the file RatchetClamp_Rectangular_Parameter.f3d and change the parameter extension for extending the length.
