TV foot risers to lift your screen above a soundbar
Lifts your TV just enough to slide a soundbar underneath instead of in front of the screen. The long, rounded feet have a shallow recess on top, and the sides flare out for a wide, steady footprint. Set the soundbar height and the lift follows.

Parts
- riser ×2 · PETG · Flat base on the bed, pocket facing up; no supports
One per TV foot. At the defaults each is 54.3 x 174.3 x 34.5 mm, about 70 g and 1 h 36 min at 2 walls / 15% infill. PETG rather than PLA because it creeps less under a constant load and copes better with heat from the TV.

Hardware
- 8 × Self-adhesive rubber bumper pads, 10 mm diameter, 2.5 mm thick · 4 per riser for blade and plate feet (one at each end, one each side), 5 per riser for V feet. Each sits in a 1 mm deep recess and stands 1.5 mm proud. That 1.5 mm is included in the lift. Set the Rub
- TV anti-tip strap or wall tether · Fit one with any riser, especially where there are children or pets.
Assembly
- Measure the bottom of one TV foot: its length front to back, its width (for a V foot: the arm width and the tip-to-tip spread), and pick the shape. Measure the soundbar height and the current gap between the furniture and the bottom edge of the screen. Set the sliders, including your rubber pad size
- Make sure the 'Screen clears the soundbar' and 'Tips no easier than on its own feet (estimate)' checks pass. If the lift you need is over 60 mm, use a different soundbar position or stand instead.
- Print two risers in PETG, pocket up.
- Press a rubber bumper pad into each recess underneath. The end pads set the tipping edge, so don't leave them out.
- With a helper, lift the TV, set a riser under each foot so the foot drops into its pocket, and lower the TV straight down.
- Attach the TV's anti-tip strap or a wall tether.
Good to know
- Raising a TV raises its centre of mass. The tip angles are engine estimates, not tests: at the defaults, 11.1 deg on the risers vs 10.6 deg on the stock feet, pivoting on the outer pad edge. Always fit an anti-tip strap or wall tether, especially around children or pets.
- The tip estimate assumes the feet run front to back, the TV's centre of mass sits over the middle of each foot, and the screen centre is about half the panel height above its bottom edge. It also assumes the end pads are fitted in their recesses. A TV whose feet run side to side, or that leans well
- The lift includes the rubber pads standing proud (1.5 mm with the default 2.5 mm pads in 1 mm recesses). If you use different pads, set the pad thickness slider, or the lift changes by the difference.
- The total lift is kept between 10 and 60 mm. If your soundbar needs more than 60 mm, the clearance check fails rather than building a taller riser.
- The load is checked for TVs from 5 to 40 kg spread over two feet. Not for TVs heavier than 40 kg, TVs on a single centre stand, or feet that touch the furniture only at small points.
- The pocket copies the outline you enter with 1 mm clearance per side. Measure carefully: a foot more than 2 mm larger than entered will not fit. V feet are modelled as two straight arms with a rounded crotch.
- A long foot combined with a tall lift and a small screen can make the riser longer than a 256 mm bed. For example, a 220 mm foot with a 100 mm soundbar on a 32" TV comes to 279 mm, so check the Print tab before printing.
