I wanted to put my Logitech X-210 horizontal, so that they fit under my monitor and not behind. Created this horizontal stand that can be glued onto the X-210 speaker using double-sided tape. If that doesn't hold, then there is a mounting screw hole as well.

Four silicone feet of at least 4 mm height can be mounted on the underside, to make it less slippery.

Print settings:

• Layer height: 0.2mm
• Material: does not matter
• Infill: 25%

Printed this on my Anet AM8 in PLA.
