This really is my second take on the Electromagnet Foundation after having seen brand spanking new screencaps of the Guardians of the Galaxy DVD. I believed the 'foundation' that the orb magnetizes down onto was a solid triangle, but nonetheless, it rather seems to be three prongs
Print three (3) of the corner bit models, and three (3) of the flaps. Paste the two corner bit assemblies together - they've guide holes in order to place pins into them to be sure you line them. Paste the two halves of every flap together facing out (significance, the smooth sides go together). The 3rd section of the flap model should snap into place, and may be fixed in both holes with M2 screws - I use 4mm long ones. You'll want three spans of 3mm metal pole - I bought a group off of Amazon for just a couple dollars. Paste the stick into the corner bit, slide the flap hinge over the pole, then cut the pole to the correct length and paste the other corner bit on.
