This functional platform jack prints fully assembled without supports. UPDATE [7/21/2015]: We have uploaded an updated platform jack with stronger scissor arms, improved axles to stop the arms from separating, and a larger gap between the screw and crossbeam to fix the fusing issue. We printed the updated version with a 0.3mm layer height and 15% infill in 4 hours. UPDATE [7/22/2015]: For anyone having problems with the scissor arms fusing together we have uploaded a modified file with the tolerance increased from 0.5 to 0.65 mm (The axle tolerance is unchanged).
