SummaryA 3D printing merit badge & charm perfect for recognizing participation in workshops and seminars. Makes a great give away print. Can be printed in different colors and awarded for different skill levels. White for an introduction/awareness of 3D printing, Blue/Green for printing of an existing design, Purple/Brown for customizing/designing/printing their own idea, Black for publishing an original design online. Profile is curved as letters were intersected with a half-sphere. Shows the stepped layers of 3D printing process. Files include a variation without loop that can be used to create a charming refrigerator magnet.InstructionsLetter/number/half-sphere/thin tube primitives made in TinkerCad. Exported out and then imported into netfabb studio trial version for the Boolean intersection of Letter/number/half-sphere and then boolean union with thin tube. Having trouble with boolean operation in TinkerCad because bits of thin shell are often left behind.
