3D Printing Merit Badge

pinshape

A 3D printing merit badge and charm is perfect for recognizing participation in workshops and seminars. It makes a great giveaway print that can be printed in different colors, awarding participants at various skill levels. White represents an introduction to awareness of 3D printing, while Blue/Green signifies the printing of an existing design. Purple/Brown awards individuals for customizing/designing/printing their own ideas, and Black recognizes those who publish an original design online. The profile is curved as letters intersect with a half-sphere, showcasing the stepped layers of the 3D printing process. Files include a variation without a loop that can be used to create a charming refrigerator magnet. Instructions: Letter/number/half-sphere/thin tube primitives are made in TinkerCad. They are then exported and imported into Netfabb Studio trial version for the Boolean intersection of letter/number/half-sphere, followed by a boolean union with thin tube. Troubleshooting: If you're experiencing trouble with boolean operations in TinkerCad, bits of thin shell may be left behind.
