Summary Customized version of http://www.thingiverse.com/thing:87132 Created with Customizer! http://www.thingiverse.com/apps/customizer/run?thing_id=87132 Printed in ABS, and set to 1.2 times larger in X and Y direction on the printer before slicing it. Post-Printing The band was too large for my wrist. After printing, and a bit of filing to make the watch pin holes thin enough to fit a pin to my watch, I found that the band was too large. I cut one side almost in half, then used acetone to glue the two pieces together. Remember, this was printed in ABS. This made one band about half the length of the other band, which was the correct size for my wrist. Good luck ! Instructions Using the following options in Customiser: strap_width = 24 strap_length = 24 pin_radius = 1.2
