Watch band keeper

Keeper for a watch band. I used flexible filament to print this, this allows the keeper to grip the excess strap. I haven't tried with rigid filament so I don't know how well it will work.

To use:
1. Fire up customiser
2. Measure the width of the strap in mm. Enter this value in the **Inner Width** field.
3. Measure the thickness of the strap in mm. Multiply this by 2 and enter the value in the **Inner Height** field.
4. Enter the **Depth** of the keeper in mm. This is the dimension of the keeper along the strap.
5. Enter the **Thickness** of the keeper, i.e. the distance between the inside and outside surfaces of the keeper. 1mm works well.
6. Select the **Edge Type** You like; squared or rounded.
