A Cryptex made for our geocache. The rings are hard coded. Print time was about 20 hours.Print 12 abstandsring_p and glue always two of them together. (back to back) Print huelse_gross and remove the support legs and the small rods in the slot. Print 6 rings with the code you want. Remove the support material so that the bottom looks like the top. Print huelse_klein and remove the support legs. Put one ring on huelse_gross followed by a double abstandsring_p. repeat this to the end. Glue the last abstandsring_p to huelse_gross. Wait until the glue is dry. Adjust the position of the rings and insert huelse_klein. Have fun.
