The smartcore is the second project from Smartfriendz. After the smartrap and its all printed structure , this is another kind of project : coreXY made cheap and easy to build ! You will find here everything to build one as easy as order some wood on the local store and print a few parts. Design is made so you don't have big operations on the box ( no drill or cut), just build the box, assemble parts separately and integrate Z and XY in the box with simple wood screws. It seems to be expandable from 20x20 to around 50x50 cm ( more to test ) . It is GPL ( as all our projects). More importantly , the all design is entirely written in openjscad with a lot of options like nema size, rods size, printable size and wood thickness . All models are dynamically updating from parameters. Print plates are also automatically generated ( not complete now, but almost done :) .Have fun to dig around with parameters ....
