Needed to fix a problem on old XBOX 360 related to DVD not ejecting. Lots of good info on Web on how to open case, unfortunately, I didn't have time to wait for tool. Found similar tool on Thingiverse, but it was not correct dimensionally when printed.
Printed on Mendel Max 1.5+ using PLA. Printed at 0.2 Layer height. Print two so that you can insert into all case locks. I was surprised that it worked so well, heard "click" once fully inserted and clips inside xbox 360 were dis-engaged.
