SummaryMy watch strap keeper had broken and even though a new one only cost a little, I thought I would create one with my Da Vinci. I am happy with how it came out so thought I would share it with you. I have included the openScad file so all you need to do if replace the variables with that off your watch. InstructionsThis can be printed with no supports and only need a small fill (about 10 - 15% should be enough). Unclip the catch using a pin and pass the keeper over the strap and then replace the clip. This should then hold the straps together whilst your watch is on your wrist
