Parametric set top box foot pedestal

pinshape

Two problems plague my household: 1) my Comcast DVR rests on the lower shelf of our media cabinet, and the door frame obstructs its IR receiver, and 2) in the master bedroom, set-top boxes are stacked, allowing anything with ventilation on top to overheat. I designed this parametric foot pedestal to adapt for use with any set-top box. I hope it works for you as well. Instructions: All variables in the OpenSCAD file that require adjustment can be found at the top of the .scad file. Their names are self-explanatory, but here's an overview: top_od: This variable determines the outer diameter of the pedestal's top. top_id: This variable sets the inner diameter for the recessed area on top, accommodating rubber feet at the bottom of your set-top box. If you don't need it, set this to 0. top_hole_depth: This variable controls how deep the recessed part is. lower_od: This variable determines the diameter of the pedestal's base. lower_ring_id: If you want to use an o-ring, this variable sets its inner diameter. I used McMaster part #4061T165, which has a square cross-section. lower_ring_od: This variable sets the outer diameter of the o-ring. oring_thickness: This variable determines the thickness of the o-ring. oring_exposed_thickness: This variable controls how much of the o-ring is exposed below the pedestal's bottom. height: This variable sets the pedestal's height.
