The only power supply I had laying around was a 600 watt with a downward facing fan, therefore I was unable to put it inside of my MakerBot. I guess I could have but I don\'t like setting things on fire. I made these simple legs and attached them to the four corners of the base. Once I make the hole for the fan and put the power supply in I will add some other pictures. Designed in NX5..... once I remember how to rotate an object without copying it I will post some new files.
Figured it out, new file is up. I had to file the m3 holes when I used the last version. You shouldn't need to with this one.
Print, eyeball positioning to the four corners, drill 2 holes per leg, attach with m3 bolts and nuts. I used Infill of 0.60 and they are pretty solid, should have no problem holding the MakerBot off my desk.
