The Moon Puzzle - v2

The Moon Puzzle - v2

updated version: higher resolution, integrated numbers

A 240 piece 3D puzzle of our moon based on real elevation data
(a smitch exaggerated for dramatic effect).

Diameter: 200 mm (8 inch)
Print time: days..!
Models: pre-arranged on 4 standard sized build plates (200x200mm) (Update: More build plate configurations can now be generated using the reconfigurator)

A lot of fun to put together and quite challenging without the use of a cheat sheet.

Not to mention that it makes for an eye-catching piece of decor sitting on your desk or on a shelf when it's fully assembled.

Enjoy!

In order to successfully print this model your printer needs to be tuned to produce accurate dimensions and retract reliably without too much oozing.
Before you decide to get the full model I recommend to download the four test pieces, print them out and test the fit. Use them to tune your settings until the pieces interlock with a nice friction fit.
