Military Style Watch Band Loop

I bought a "PATROHOO" replacement strap for my Suunto Core watch in 2017 and again in 2019. I wore the first strap completely out but on the second one just the loops or watch band keepers have worn out. So I used FreeCAD to design some replacements and printed them in Black TPU. They appear to be way stronger than the original ones. The inside measurements are 25mm x 4mm at the outer edges and goes up to 6mm in the center.

Here is the Amazon description for the watch band:

Clean up and assembly...

Depending on how dry your TPU is, you will need to clip off varying amounts of stringing and small deformities. You will also need to remove the metal buckle to get the keepers on.

*Note: The keepers should be oriented so the inside wedge allows the strap to slide easier when putting the watch on.

How I Designed This

About the design process...

I run Ubuntu Linux on all my home computers. This limits my choices for CAD software so I have taught myself how to use FreeCAD since there is a native Linux version that seems to be getting more stable as time goes by.
