Parametric set top box foot pedestal

SummaryTwo problems exist in my household: 1) my Comcast DVR is on the lower shelf of our media cabinet, and the door frame blocks the IR receiver, and 2) in the master bedroom we have our set-top boxes stacked, so anything with ventilation on top can overheat. I designed this parametric foot pedestal so it could be altered for use with (hopefully) any set-top box. I hope it works for you, too.InstructionsAll of the variables in the OpenSCAD file that you might want to adjust are at the top of the .scad file. The names are pretty self-explanatory, but here's an overview of what they do: top_od: the outer diameter of the top of the pedestal top_id: the inner diameter for the recessed area on top. This is to accommodate the rubber feet at the bottom of your set-top box. If you don't want it, set this to 0. top_hole_depth: how deep the recessed part is lower_od: the diameter of the base of the pedestal lower_ring_id: the inner diameter of the o-ring, if you want to use one. I picked McMaster part #4061T165, which has a square cross section. lower_ring_od: the outer diameter of the o-ring oring_thickness: the thickness of the o-ring oring_exposed_thickness: how much of the o-ring you want exposed below the bottom of the pedestal height: how tall the pedestal should be
