Printed with a 0.4 nozzle in 0.12 High Quality, no brim, 5 wall loops, Matte PLA.
The print came out nice and the clasp separated with little force and no fear of cracking anything. When closed, the lid has a little bit of play which might result in rattling when shaken -- a separate model with tighter tolerances might be helpful there?
The .emf had the clasp as a separate object which OrcaSilcer suggested to combine into a multi-part object. This is needed so the clasp stays on position. Only after combining the objects, I could lay it flat on the print surface. Maybe update the .emf file for convenience :)
