So I just was given the i3 plus and want to make and print minis for D&D characters and such, everything I have read say the Cura 2.1 is the best option. If so where can I get it and if now what is the better option.... Im new to 3d printing but do have a pretty good computer(gaming) and it might be a little more advanced than the i3, I honestly dont know. Is there any help, if so please let me know, Thanks in advance and much appreciated...
