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
you need brass or pcb spacers of 5 or 5.5 mm for the leg pivots... also to mount the motors you need a 6x3mm pipe cut to length to clamp the motor mounts on
