My mother likes garage/yard sales. Over the years she has purchased some questionable items... This time around was a nice glass curio cabinet that just happened to be missing almost all of the original plastic clips that held the glass sides in. She calls me up has me drive over and says print this. first test print was closest to original design however lacked enough surface area for leverage. couple more versions fiddling with tinkercad and she is happy. out of the 24 original clips 3 existed. the rest were broken or whatever scraps of metal the previous owner could find.
