About this 3D model

This is a simple adapter for the Garmin 2.3mm pinhole, to shift the size down to 1.5mm. I made it for a Garmin Forerunner 965 and a spigen Galaxy watch band. The pin does not contact the walls of the pinhole because it has a 0.2 mm bottom layer. I printed it using a 0.2mm hotend from ASA. I was not sure if TPU could be used for such a small item. For the perfect fit, the bottom layer had to be profiled a bit.
