This is a half of a hydraulic ramp i modeled for a 1990 Honda Civic EF from HWCity/Hotwheels.
Print the STL two times (two stands, two slider, four arms).
Small piece of cardboard or a small drop of glue hold the slider in place
(if it should stay elevated with car on the arms)
Pins on the slider could be lightly melted to fix the arms or to avoid accidently dissassembly.
Prints fairly easy.
