This is a replacement Golf Ball Marker that snaps onto your golf glove. I lost my marker and thought I might try to print one. Attached are two different designs; one with a smiley face :) and one plain one. I also included the original Inventor file.I quickly designed the button snap feature and it was a tight fit after coming off the printer. I just slightly filed it to the point where it was not too tight but tight enough not to fall off.I created the parts in AutoDesk Inventor, so I posted the .ipt file along with the two .stl files.**Caution Notice: This golf device will not improve your golf game in any way ;)1.) Print (or Modify and then Print). 2.) After cleaning up the part you may need to file the button down to get the snap to work correctly. 3.) Go Golfing!!My prints were made on an Afinia UP! PP3DP printer.
