For the three hundred seventeenth edition of the GeoGearHeads cnlson, Anteaus, LANMonkey, and ChrisOfTheNorthWest take another look at 3D Printing for Geocachers. They started with a question from CodeJunkie about CAD software. Anteaus mostly uses Tinkercad and cnlson also likes Fusion 360, but points out the "20 Best 3D Printing Software Tools (All Are Free)" list from All3DP. They also talked about when the different materials become brittle and used Omnexus's article "Ductile/Brittle Transition Temperature" as reference. Anteaus also talked about his "Pine Cone Cache" posted to Thingiverse. The live video session from this Google+ Hangout On Air can be found on YouTube.
