These adapters convert the ridiculous mounting footprint on the PlayStation 3D display into a standard 75x75 footprint one adds the standard 100x100 footprint to it too, but I liked how I got the 75 to sit in the grid on the back. anyways the tv uses 4 M3 bolts for mounting for some reason so I used four M3*20's bolts with washers. goes without saying but its best printed with high to 100% infill since its gotta hold a tv. I did print with supports for the recessed m3 bolt holes.
I added holes that line up with the speaker/subwoofer so shouldn't affect sound, no clue what that little hole goes to but it's on the back of the tv so I made the hole for it. Added a recess for the PlayStation logo to sit in since it protrudes, gave me a good spot to label this thing too.
Now on mine I had to drill out the holes for the m3 bolts to get the screws through and I pressed the nuts that came with my arm in after deburring to get them in and friction let me tighten them appropriately, but the shape of the nuts didn't allow for hex holes otherwise id have done that. I believe I corrected the hole sizes a bit but just be aware there may be some minor fitting/drilling required and different arms may have different hardware sizes.
Mine was printed with PLA at 50% infill but I'd recommend higher infill to be safe but in all honesty i think these cheap M3 bolts will break first who the heck designed M3's for a tv. anyways it's been hanging for 2 months now and handles me moving the arm around, so I figured it was time to upload it.
