Carlift for dioramas to print in 3d scaleable 3D print model

For my diorama i designed a carlift, oriented at the Nussbaum HF-3000 DT but not 100% scale. The height of the arms is adjustable, but armsupport needs to be glued in position. not movable later.

scale is 1:24 /1:25.

to print: 1x Pillar_1 1x Pillar_2 1x armsupport_1 1x armsupport_2 2x arm_long_1 2x arm_long_2 2x arm_short_1 2x arm_short_2 4x pin 1x pump_oiltank

additional to the printed parts i used: 5mm steelrod 120mm long, 2 pieces (to prevent the part from bending and position it at the diorama base. 3mm clear acrylic rods to put them beneath the arms (arms are very slim and would bend over time) 4 pieces needed. length varies on desired height.
