Designed this simple riser to slip under the feet of my Samsung TV (6 Series LED Model). I made these because the Yamaha Soundbar I have in front of the TV blocks the IR signal for the remote while you're sitting.

It might be a good idea to use some anti slip mat underneath since it slides more easily with risers installed. However, I haven't had any issues personally.

If you need more or less height, you can scale it in your slicer in the Z axis. Currently it is designed to raise the TV about 16mm.
