NOTE: For al that have downloaded this project, I was not happy with the way the Keys were draging in the keyway. I made some changes that freed up the rings and allowed the use of full keys on both sides. Please download the new TopCap (if you have not already printed) andythe new Keys.
This is a combination lock Brain Teaser Puzzle Bank that I designed and built. I went to an Escape Room Game and one of the escape clues was contained in a Brain Teaser Puzzle Bank with 5 alphabet rings. This inspred me design my own device. I used Inventor to draw all the parts. The outside dimension is about 4.25 inches or 108mm. The inside space is about 60mm.
There are 6 print files, but 2 of them (Alpha Ring and Spacer Ring) need to be printed 5 times. These items take a while to print.
The design is simple.
The Alpha ring has 2 parts, the alphabet ring and the slot ring. To select the desired character for that ring, align the slot to the letter and slide it on the LockerCup. The bottom ring is the left most character. Set the desired character for each of the remaining rings. After all 5 rings are place on the cup, the CupCollar is place on the top (with the arrow pointing to the selected characters) and fastened with 2-#6x1" pan screws. Some minor adjusting of the Alpha rings may be needed to align the slot for the key.
