The first AARP "Dynamic A" logo whistle is working! Thanks to my pal Doug Duarte in ITS for the long term loan of the MakerBot Mini to the innovation lab and for suggesting that the logo be made into a whistle. I created the logo outline and the shape of the interior air cavity in the non-cloud version of Adobe Illustrator. Then I imported both SVG vectors into TinkerCAD and set the air cavity shape as a "hole." The resulting model was sent to the Thingiverse site and then downloaded into the MakerBot software on my laptop for printing. This red one with lug took 40 minutes at standard settings with dimensions set at X: 50.75 mm, Y: 36.10 mm, Z: 8.00 mm, medium resolution. Tur
