This is a replacement watch strap keeper, this one is a rough replica of the watch strap keepers that came with my Traser H3 P96 Outdoor Pioneer, please see the attached drawing to determine whether this component is suitable for your needs. I printed this part in TPU for flexibility.
I used a mid print pause to print the strap keepers around the watch strap. If you do this please carefully look at the planned travel moves and the g-code used for the pause.
On my Prusa i3 MK3s I used this code in the 'After layer change G-code' box in PrusaSlicer.
'''{if layer_num == 88} M300 ;ACTIVATE BEEPER G1 X10.000 Y200.000 E0; parking position M1; user stop G28 Y; Home Y axis M105; return to current temp {endif} '''
