Options for raising Sonos Arc?

[Comacchio]

Our new TV unit sits 41 cm off the floor, bottom of the TV is 64cm from the floor - Sonos Arc sits directly on top of the TV unit at the moment but looking to raise it a little to try and hide the sockets under the TV (Top of sockets are 53 cm, so raising the Arc to this level still allows the 4" recommended clearance to the bottom of the TV.

So I need to find a way to raise the Arc by about 47mm - was thinking about getting somebody to 3D print a base for the Arc to sit on? Is this likely to cause sound quality issues? What other options do I have?

Cheers.
