EARTH PUZZLE

This is a multi color model of earth which can be printed on a single extrusion printer.  The earth pieces are printed flat and a color change is needed starting at layer 20. You can do this by pressing the + icon on the sidebar at layer 20. Needless to say you will need to be present when the printer reaches this layer to switch the fillament manually. I use a brim to make sure the smallest pieces stay on the buildplate. If you want to use the magnets you will need to order 56x a 5x2mm magnet. Something like these:  Amazon link to magnets For the core I used M3 nuts. make sure they are made of steel (and not stainless steel). For example: Amazon link to nuts (I personally did not buy from amazon) I glued in most of the nuts and magnets. The direction of the polarity of the magnets is not important. I decided not to try and achieve a press fitm, because some printers would probably print the holes too tight. For other instructions please see this video. It's pretty self explanatory… Youtube Short Video  Edit 07/05/2023: added a stronger stand (stand_v2) /Print Challenge/
