thingiverse

published a time before Valentine day, you have time to make one. This is not a day-before project, do your project start a month before you need it! Weight 51 gram (complete). How to make: print all pieces as shown. corner.stl: print with support material. core.stl: do not print support inside the sphere! Try to get good adhesion to printbed. Maybe you need some glue around after print start. Remove all plastic blobs and sharp edges. I don't have sandpapered. assembly: You will need 4pcs screws M3 and nylock nuts. Tool: 1 long M3 screw or threaded rod. Come with M3 rod thru the sphere, add a nylock nut from the other side and pull this nut in the inner hexagon holes. Do not push a nut without guide rod, it will be lost inside. Complete it, screws may be lubrificated with vaseline. Other sides should be lubrificated after paint/sticker. Close all screws to end, puzzle is blocked. Open again all screws by 1/4 turn, check if rotates, repeat. if you like, insert stopsel.stl to screwholes at the end. if you like, don't assemble trivial_edge.stl and this is a hexagonal puzzle. There are holes for screw head in the edge. Paint it or sticker. Lubrificate all moving tracks. Twin project: https://www.thingiverse.com/thing:3219527 https://www.thingiverse.com/thing:2750996
