Super PI Box

thingiverse

This unique box combines elements of the Easy as PI box (http://www.thingiverse.com/thing:3817) and the A-Mazing Box (http://www.thingiverse.com/thing:1481). The combo is as simple as calculating PI to 15 figures - that's 3.14159265358979. To use it, print all the pieces and attach Ring3 to the Base, Ring2 to Ring3, and Ring1 to Ring2. The ticks represent 0-9, with 3 being the fourth tick, 1 the second, and so on. Align these with the first three digits of PI from left to right, with the Base on the left and the lid on the right. Push the lid out one stage, then repeat for the next three digits until it comes free. If you encounter issues, separate the Base from Ring3 for access. Some sanding may be needed for a smooth fit.
