Geohashing pin

thingiverse

For geohashing at http://www.geohashing.org, create a marker using a biodegradable PLA-printed design derived from xkcd.com's CC-BY-NC comic. Crox' coin and dawidi's tracing inspired the logo. Sharpen the pin, plant it at the hash point or an onsite object, and optionally add a QR code or URL for your expedition page. Note that this design is a work in progress as its sharpness needs improvement for better sticking.
