Publish your project early, before Valentine's Day is here to save the day. You have time to make one - this isn't a last-minute project, start it a month before you need it! The finished weight is 51 grams. To make it: Print all parts as shown in the design. Corner.stl: Print with support material. Core.stl: Don't print support inside the sphere. Get good adhesion to the print bed. You might need some glue after printing starts. Remove plastic blobs and sharp edges. I don't have a sander, but you should sand it for a smoother finish. Assembly: You'll need 4 M3 screws and nylock nuts. A tool is required - an M3 screw or threaded rod will do. Insert the M3 rod through the sphere, then add a nylock nut from the other side. Pull the nut into the inner hexagon holes. Don't push a nut without a guide rod, it'll get lost inside. Complete the assembly, and lubricate the screws with vaseline. Other sides should be lubricated after painting or sticking on the design. Close all screws tightly, then open them by 1/4 turn to check if it rotates smoothly. Repeat this process until it's smooth. If you like, insert stopsel.stl into screw holes at the end. You can choose not to assemble trivial_edge.stl and have a hexagonal puzzle with holes for screw heads on the edge. Paint or sticker your design. Lubricate all moving parts for a smoother experience.
