<p><i>This is imported from Thingiverse</i><br><br>The (2018 model) Vizio P65-E1 TV I have is designed to blast sound off a wall and reproject back to you. Well, this doesn't work if you turn your TV away from a wall, and can be quite annoying if you are sitting behind it when someone cranks the volume because they cannot hear it. I designed this to help redirect and amplify the TV's audio to the front of the TV. It works well but it's no soundbar.</p><p>The design fills the gap between the feet of the TV and the display above it while remaining flush to the front of the display itself; requiring no need to mount or tape anything (unless it's not on its feet). I measured and modeled to very tight tolerances, you may want to keep this into consideration (so finishing might be required).</p><p>I'm including two designs I made, one that uses a fair amount of bridging, and a more open version that only uses three perimeters to clear the center gap. I didn't use supports inside the speaker for either, but if your printer cannot bridge well you may want to.</p><p>Ultimately, I'm using one of each design on my TV. The non-bridge version came as an idea to reduce plastic while I was printing the first version. They provide a good amplification effect, and any difference between the two is unnoticeable.</p><h3>Print Settings</h3><p><strong>Printer:</strong></p><p>Sainsmart Coreception 300 / Creativity ELF (Saving my pennies for the upcoming XL)</p><p><strong>Rafts:&nbsp;</strong></p><p>No</p><p><strong>Supports:</strong></p><p>Yes</p><p><strong>Resolution:&nbsp;</strong></p><p>0.25</p><p><strong>Infill:</strong></p><p>0%</p><p><strong>Filament:</strong></p><p>White Sainsmart PLA</p><p><strong>Notes:</strong></p><p>You'll need two of these!!! I printed this model on it's back and used Tree Supports in Cura for the overhangs. I ran this at 120 mm/s because this doesn't need to be pretty, Cura gave me a 4-hour print estimate, but it took me 7 hours 12 minutes (reduced bridging model). I printed this with 0% infill at 3 perimeters thick with a wall thickness of 0.4mm on a 0.4mm nozzle.</p><p>If you have a small build area, you've been warned. The max dimensions are 145mmX130mmX150mm.</p>
