Some Assembly Required Mystery Cache

I recently and delightedly came upon Marc Vigo Anglada’s wonderful instructions for making an origami box and sought his permission to direct cachers to http://www.lsi.upc.edu/~marc/Origami/box.pdf to share this delight.  Print the image below, carefully cut out the square, use it to make your own box and find the unit and decimal minutes* of this geocache.

NOTE March 31, 2018: cache is now 16 meters south and a little east of where your computed decimal minutes take you.

You can check your coordinates at GeoChecker.com.

p.s. fradjoh kindly sent me the following link to a video that does a super job of explaining how to build the box: https://www.youtube.com/watch?v=JAwDT1VWYcY[/url]

p.p.s. I did not originally intend this to be series, but I got so hooked on this folding stuff, thanks to the guy who does the video that fradjoh kindly sent, I've done two more: Some Assembly Butterfly (GC54MC2) and Some Assembly BalloonBox (GC54MKH). Will there be more? Hmmmm....

NOTE JULY 24, 2018 - See BurscHam's kind log from today wherein it is noted that the cache is now 13 metres directly southeast of the solved coordinates.

* ie. the last four digits of the N and the last four digits of the W coordinates
