So far I've only printed this once. I used black 3mm PLA from Monoprice on an Ultimaker2. (unmodified, except with a narrower spool holder to accommodate the Monoprice spool). I had two issues. The first was a slight error in the design, which I has already been corrected in the STL. (the front-to back dimension was slightly too tight, so I had to do a bit of filing) The second issue was that there is some material missing from the bottom, most notably the back edge of the front left foot (you can see this in the photo). I think this was caused by not laying down enough glue on the bed, and the print lifted in these areas.
Before designing on my computer, I drew up this quick whiteboard sketch. (Yes, I know my perspective is all wonky.) The design evolved quite a bit after this, but you can see the idea of the curved legs with the 3-ridge motif to match the PS2, and the ventilation channel in the bottom. Later I extended the length so that the PS2 won't slide of the front or back, and added a grille on the front with similar styling.
I used OpenSCAD, but this is a screenshot from Cura (which has much nicer rendering, IMHO). I tried to come up with something that is easily printable (there are absolutely no overhangs), doesn't use too much material (or printing time), provides good ventilation, provides adequate support for the PS2 so it won't tip over, and finally matches the look of the PS2.
