this is a model for a full size table that i had designed to be made in bamboo https://www.youtube.com/watch?v=XUmu_xiiwMI http://hackaday.com/2013/12/04/crab-ble-a-table-that-walks/#more-108937 print all the parts at 0.25 mm layer height using a .4 or less nozzle.. the parts are interconnected using a m3 threaded rod and nuts ... the battery holder is mounted in the center.. print 6 sets of the leg set and 2 sets of the cross brace set.. for anybody interested in making it i woulf be making a detailed assembly diagram. the motors are optional .. the model can be moved manually also if needed.. i used 1:100 ratio 6v geared dc motors.... also a lot of plastic lubricant is needed and it tends to jam up the legs are joint together using m3 x 12 mm hex nut and bolt
