Nailbox Geocache

thingiverse

You also need : - 6 Nails 40mm long, 2mm diameter - 1 Nail 25mm long, 1,5mm diameter" The Caches name is "Hast du den Dreh raus?" which means sth. like "Do you know the right turn?". The four knobs are fake knobs. The Cachers will turn the knobs on the side and above to open the box, but the real turn is the centrifugal turn of the cache itself. Then the box will open. You should print the box and the lid without any support. Print the lid upside down. As the printer comes to the layerheight, when the nailholes are almost printed closed, you have to put the nails (40mm) into the nailholes. Watch out and put them into the right holes, so that the nails are able to slide into the other sides holes. After printing you have to put the sideknobs through the side holes of the box. When they are positioned, take a lighter and warm the inner end, until it is melting a little. Use a knife or something else out of metal and squeeze the warm end a little, so that it is getting thicker. Now it shouldn`t be possible to move the knob out of the box again. The upper knob: Put the smaller nail into the hole above, push it into the upper lid from above, and bend it on the inner side (with a hammer, or pliers). Now the geocache is finished. Have fun and happy Caching
