Good morning. I am doing the 3D-printed version of the robot. The .stl files I have downloaded only contain one(1) file for J2 Arm. But that does not fit on my printer (300Dx300Wx290H). Other people on the forum talk about epoxy the two(2) parts of the J2 arm together. Where can I find the two files for the J2 Arm? Thanks in advance. Cheers. sMarius.
